question
perform the operation.
(2x² - 3x + 1) + (7x² + 10x + 8)
answer

Explanation:

Step1: Remove parentheses

$2x^2 - 3x + 1 + 7x^2 + 10x + 8$

Step2: Combine like $x^2$ terms

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

Step3: Combine like $x$ terms

$-3x + 10x = 7x$

Step4: Combine constant terms

$1 + 8 = 9$

Step5: Assemble final polynomial

$9x^2 + 7x + 9$

Answer:

$9x^2 + 7x + 9$
