question
perform the operation.
$(2x^2 - 6x - 5) + (-9x^2 + 5x - 4)$

Explanation:

Step1: Remove parentheses

Remove the parentheses from the expression: \(2x^{2}-6x - 5-9x^{2}+5x - 4\)

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

Combine the \(x^{2}\) terms: \(2x^{2}-9x^{2}=(2 - 9)x^{2}=-7x^{2}\)

Step3: Combine like terms for \(x\) terms

Combine the \(x\) terms: \(-6x + 5x=(-6 + 5)x=-x\)

Step4: Combine constant terms

Combine the constant terms: \(-5-4=-9\)

Step5: Combine all results

Combine the results from Step2, Step3, and Step4: \(-7x^{2}-x - 9\)

Answer:

\(-7x^{2}-x - 9\)
