$9x^{2}-4x+2$
$\underline{+7x^{2}+8x-3}$

the answer is $\square$.
(simplify your answer.)

Explanation:

Step1: Combine $x^2$ terms

$9x^2 + 7x^2 = 16x^2$

Step2: Combine $x$ terms

$-4x + 8x = 4x$

Step3: Combine constant terms

$2 - 3 = -1$

Step4: Sum all combined terms

$16x^2 + 4x - 1$

Answer:

$16x^2 + 4x - 1$
