perform the operation.
$(3x^2 - 3x + 9) + (-5x^2 - 8x - 7)$

Explanation:

Step1: Remove parentheses

\(3x^2 - 3x + 9 - 5x^2 - 8x - 7\)

Step2: Combine like terms for \(x^2\)

\(3x^2 - 5x^2 = -2x^2\)

Step3: Combine like terms for \(x\)

\(-3x - 8x = -11x\)

Step4: Combine constant terms

\(9 - 7 = 2\)

Step5: Combine results

\(-2x^2 - 11x + 2\)

Answer:

\(-2x^2 - 11x + 2\)
