Question

question
perform the operation.
$(-10x^2 + 4) + (-9x - 6)$

Explanation:

Step1: Remove parentheses

To add the two polynomials, we first remove the parentheses. The expression becomes $-10x^{2}+4 - 9x - 6$.

Step2: Combine like terms

Next, we combine the constant terms. The constant terms are $4$ and $-6$. Combining them gives $4-6=-2$. The terms with $x^{2}$ and $x$ remain as they are since there are no other like terms. So the simplified expression is $-10x^{2}-9x - 2$.

Answer:

$-10x^{2}-9x - 2$
