Question

perform the indicated operation.
(-5x - 7) + (6x² + 5x + 11)
(-5x - 7) + (6x² + 5x + 11) = \square (simplify your answer.)

Explanation:

Step1: Remove parentheses

We have \((-5x - 7)+(6x^{2}+5x + 11)\), removing the parentheses gives \(-5x - 7+6x^{2}+5x + 11\).

Step2: Combine like terms

For the \(x\) terms: \(-5x+5x = 0\). For the constant terms: \(-7 + 11=4\). The \(x^{2}\) term remains \(6x^{2}\). So combining like terms we get \(6x^{2}+4\).

Answer:

\(6x^{2}+4\)
