Question

simplify.
$(2w^{2} + 7) + (w^{2} - 4w - 3)$

Explanation:

Step1: Remove parentheses

$2w^2 + 7 + w^2 - 4w - 3$

Step2: Combine like $w^2$ terms

$2w^2 + w^2 = 3w^2$

Step3: Combine constant terms

$7 - 3 = 4$

Step4: Assemble simplified expression

$3w^2 - 4w + 4$

Answer:

$3w^2 - 4w + 4$
