Simplify the following expression: (5x2 + 3x + 4) − (2x2 + 5x − 1). If the final answer is written in the form Ax2 + Bx + C, what is the value of A? The 2 be hide 5x is squared and so is the one by 2x

Best ResponseYou've already chosen the best response.1Right! So your equation would be 3x  5  5x  1. Can you combine the like terms?

Best ResponseYou've already chosen the best response.1Lets rearrange it so its easier to work with. Remember to keep the symbol in front of each term. 3x  5x  5  1 First off, what is 3x  5x?

Best ResponseYou've already chosen the best response.1\[(5x^2 + 3x + 4)  (2x^2 + 5x  1)\]We have to distribute the 1. \[(1)\stackrel{\Huge\curvearrowright}(2x^2 + 5x  1)\]1 * 2x^1 = 2x^2 1 * 5x = 5x 1 * 1 = 1 Now we have: \[5x^2 + 3x + 4  2x^2  5x + 1\]Combine like terms. 5x^2  2x^2 = 3x^2 3x  5x = 2x 4 + 1 = 5 And we end up with: \[\large 3x^2  2x + 5\]
