Question

use algebra tiles to find $(-7x - 6) + (2x^{2} + 8x + 8)$. combine like terms. for example, write 3 instead of 1 + 1 + 1.

Explanation:

Step1: Identify like terms

Group $x^2$, $x$, and constant terms:
$2x^2 + (-7x + 8x) + (-6 + 8)$

Step2: Combine $x$ terms

Calculate sum of linear terms:
$-7x + 8x = x$

Step3: Combine constant terms

Calculate sum of constants:
$-6 + 8 = 2$

Step4: Assemble simplified expression

Combine all simplified terms:
$2x^2 + x + 2$

Answer:

$2x^2 + x + 2$
