Question

add. your answer should be an expanded polynomial in standard form. (5h^3 - 8h)+(-2h^3 - h^2 - 2h)=

Explanation:

Step1: Remove parentheses

$5h^{3}-8h - 2h^{3}-h^{2}-2h$

Step2: Combine like - terms for $h^{3}$ terms

$(5h^{3}-2h^{3})-h^{2}-8h - 2h=3h^{3}-h^{2}-8h - 2h$

Step3: Combine like - terms for $h$ terms

$3h^{3}-h^{2}+(-8h - 2h)=3h^{3}-h^{2}-10h$

Answer:

$3h^{3}-h^{2}-10h$
