Question

perform the indicated operation.
(10x - 5) + (12x² - 10x + 7)
(10x - 5) + (12x² - 10x + 7) = \boxed{\quad} (simplify your answer.)

Explanation:

Step1: Remove parentheses

We have \((10x - 5)+(12x^{2}-10x + 7)\). Removing the parentheses gives \(10x - 5+12x^{2}-10x + 7\).

Step2: Combine like terms

For the \(x\) terms: \(10x-10x = 0\). For the constant terms: \(-5 + 7=2\). The \(x^{2}\) term remains \(12x^{2}\). So combining these, we get \(12x^{2}+2\).

Answer:

\(12x^{2}+2\)
