Question

use algebra tiles to find $(-5x - 7) - (-4x^{2} + 4x)$. combine like terms. for example, write 3 instead of $1 + 1 + 1$.

Explanation:

Step1: Distribute the negative sign

$(-5x - 7) + 4x^2 - 4x$

Step2: Rearrange like terms

$4x^2 -5x -4x -7$

Step3: Combine like x terms

$4x^2 + (-5-4)x -7 = 4x^2 -9x -7$

Answer:

$4x^2 -9x -7$
