Understanding the Problem
Before we dive into the solution, let's make sure we fully understand the problem at hand. We're given a quadratic expression, which is 3x² − 5x + 6, and our goal is to find another expression that, when added to the first one, results in 3x. Essentially, we’re trying to solve for a missing piece in an algebraic equation. Think of it like a jigsaw puzzle, where we have some pieces and a target image, and we need to find the piece that fits perfectly to complete the picture. To put it mathematically, we need to find an expression, let's call it E, such that: (3x² − 5x + 6) + E = 3x. This equation is the key to solving our problem. It tells us that if we add our mystery expression E to the given polynomial, we should end up with 3x. Understanding this equation is crucial because it sets the stage for how we will approach the solution. We need to isolate E on one side of the equation to figure out what it is. This involves using algebraic manipulations, which we’ll discuss in the next section. But for now, let’s make sure we’re clear on what we’re trying to achieve. We're not just looking for any expression; we're looking for the specific expression that, when combined with 3x² − 5x + 6, gives us 3x. This targeted approach will guide us through the steps we need to take to find the correct answer. So, with our equation in mind, let's move on to the next step: how to actually solve for E. This involves some basic algebraic techniques that will help us isolate our unknown expression and reveal its true identity. Let's get to it!
Setting Up the Equation
Alright, guys, now that we've got a good grasp of the problem, let's get down to the nitty-gritty and set up the equation that will guide us to our solution. As we discussed earlier, the core of our problem can be represented by the equation: (3x² − 5x + 6) + E = 3x. This equation is our roadmap, showing us the relationship between the given polynomial, the expression we need to find (E), and the desired result (3x). Setting up the equation correctly is super important because it lays the foundation for all the steps that follow. If we don't have the right equation, we're essentially navigating with a faulty map, and we might end up going in circles! So, let's break down the equation and make sure we understand each part. On the left side, we have our starting polynomial, 3x² − 5x + 6, which is the expression we're going to modify. Then, we have E, which is our mystery expression – the one we're trying to find. The plus sign between them indicates that we're adding E to the polynomial. On the right side, we have 3x, which is our target expression. This is what we want to end up with after adding E to the polynomial. The equals sign tells us that the left side of the equation must be equal to the right side. In other words, when we add E to 3x² − 5x + 6, the result should be exactly 3x. Now that we have our equation set up, the next step is to isolate E. This means we need to get E by itself on one side of the equation. To do this, we'll use some basic algebraic manipulations, which we'll explore in the next section. But for now, let's take a moment to appreciate the power of this equation. It's a simple yet elegant way to represent our problem, and it provides a clear path to the solution. So, with our equation in place, let's move on and start unraveling the mystery of E!
Isolating the Unknown Expression
Okay, folks, with our equation (3x² − 5x + 6) + E = 3x firmly in place, it’s time to roll up our sleeves and get to the heart of the problem: isolating the unknown expression E. This is a crucial step because once we have E by itself on one side of the equation, we'll know exactly what it is. Think of it like finding a hidden treasure – we know it's there, but we need to do some digging to unearth it! To isolate E, we need to get rid of the (3x² − 5x + 6) term that's being added to it. We can do this by using the principle of inverse operations. In algebra, what you do to one side of the equation, you must do to the other to keep things balanced. So, to remove (3x² − 5x + 6) from the left side, we'll subtract it from both sides of the equation. This gives us: (3x² − 5x + 6) + E − (3x² − 5x + 6) = 3x − (3x² − 5x + 6). Notice how we've subtracted the entire expression (3x² − 5x + 6) from both sides. This is important because we want to remove the whole term, not just parts of it. Now, let's simplify the equation. On the left side, (3x² − 5x + 6) and −(3x² − 5x + 6) cancel each other out, leaving us with just E. So, our equation now looks like this: E = 3x − (3x² − 5x + 6). We've successfully isolated E! It's like we've found our hidden treasure, but we're not quite done yet. The expression on the right side still needs to be simplified. We have 3x minus the polynomial (3x² − 5x + 6). To simplify this, we'll need to distribute the negative sign and combine like terms. This is where our algebraic skills really come into play. We'll tackle this simplification in the next section, but for now, let's celebrate our progress. We've isolated E, and we're one step closer to finding the expression we need. So, let's keep the momentum going and move on to the next challenge: simplifying the expression on the right side of the equation!
Simplifying the Expression
Alright, team, we've successfully isolated E and our equation now reads: E = 3x − (3x² − 5x + 6). The next step in our algebraic adventure is to simplify the expression on the right side of the equation. This is where we'll put our algebraic maneuvering skills to the test! Simplifying the expression involves two key steps: distributing the negative sign and combining like terms. Let's start with distributing the negative sign. The negative sign in front of the parentheses means we need to multiply each term inside the parentheses by -1. So, −(3x² − 5x + 6) becomes −3x² + 5x − 6. Remember, when we multiply a positive term by a negative sign, it becomes negative, and when we multiply a negative term by a negative sign, it becomes positive. Now, let's rewrite our equation with the distributed negative sign: E = 3x − 3x² + 5x − 6. Great! We've taken care of the parentheses, and now we're ready to combine like terms. Like terms are terms that have the same variable raised to the same power. In our expression, we have two terms with x: 3x and 5x. We can combine these by adding their coefficients (the numbers in front of the variables). So, 3x + 5x equals 8x. Now, let's rewrite our equation with the combined like terms: E = −3x² + 8x − 6. We've done it! We've simplified the expression on the right side of the equation, and we now have a clear and concise expression for E. This simplified form is much easier to work with, and it gives us a direct answer to our original question. So, let's take a moment to appreciate the power of simplification. By using basic algebraic techniques, we've transformed a complex-looking expression into a simple one. Now that we have our simplified expression for E, we're ready to state our final answer and celebrate our success. But before we do that, let's just take one more look at the steps we've taken to make sure we're confident in our solution. We started by setting up the equation, then we isolated E, and finally, we simplified the expression. Each step was crucial, and together, they've led us to our goal. So, with our simplified expression in hand, let's move on to the final step: stating the answer!
Stating the Answer
Alright, my friends, after all our hard work, we've reached the final destination! We've successfully navigated the algebraic landscape, and now it's time to proudly state our answer. We set out to find the expression that, when added to 3x² − 5x + 6, gives us 3x. Through careful equation setup, isolation of the unknown, and simplification, we've arrived at the solution. Our equation, E = −3x² + 8x − 6, tells us exactly what expression we need. So, drumroll please… The expression we need to add to 3x² − 5x + 6 to obtain 3x is −3x² + 8x − 6. How awesome is that? We started with a question, and now we have a definitive answer. But let's not just take our word for it. It's always a good idea to check our work to make sure our solution is correct. To do this, we can add our expression, −3x² + 8x − 6, to the original polynomial, 3x² − 5x + 6, and see if we get 3x. So, let's do it: (3x² − 5x + 6) + (−3x² + 8x − 6). When we combine like terms, we get: (3x² − 3x²) + (−5x + 8x) + (6 − 6). This simplifies to: 0x² + 3x + 0, which is just 3x. Yay! Our solution checks out. We've not only found the expression, but we've also verified that it works. This is a great feeling, and it's a testament to the power of algebra. So, let's celebrate our success! We've tackled a challenging problem, and we've come out on top. We've learned about equation setup, isolation of unknowns, simplification, and verification.
