Question

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

Explanation:

Step1: Remove parentheses

To add the two polynomials, we first remove the parentheses. The expression \((-10x^{2}+4)+(-9x - 6)\) becomes \(-10x^{2}+4-9x - 6\) because the positive sign in front of the second parentheses doesn't change the signs of the terms inside.

Step2: Combine like terms

Next, we combine the constant terms. The constant terms are \(4\) and \(-6\). Combining them, we have \(4-6=-2\). The \(x^{2}\) term \(-10x^{2}\) and the \(x\) term \(-9x\) have no like terms to combine with, so we leave them as they are. So the simplified expression is \(-10x^{2}-9x - 2\).

Answer:

\(-10x^{2}-9x - 2\)
