Question

add. your answer should be an expanded polynomial in standard (-t^3 + 5t^2 - 6t)+(8t^2 - 8t)=

Explanation:

Step1: Remove parentheses

Since there is a plus sign before the parentheses, the terms inside remain the same. So we have $-t^{3}+5t^{2}-6t + 8t^{2}-8t$.

Step2: Combine like - terms

Combine the $t^{2}$ terms: $5t^{2}+8t^{2}=13t^{2}$, and combine the $t$ terms: $-6t-8t=-14t$.

Answer:

$-t^{3}+13t^{2}-14t$
