question
perform the operation.
$(x^2 + 2x + 8) + (-x^2 - 3x - 7)$
answer

Explanation:

Step1: Remove parentheses

$x^2 + 2x + 8 - x^2 - 3x - 7$

Step2: Combine like $x^2$ terms

$x^2 - x^2 + 2x - 3x + 8 - 7 = 0x^2 + 2x - 3x + 8 - 7$

Step3: Combine like $x$ terms

$2x - 3x + 8 - 7 = -x + 8 - 7$

Step4: Combine constant terms

$-x + (8 - 7) = -x + 1$

Answer:

$-x + 1$
