Explanation:

Step1: Remove parentheses

$8v^3 + 4v^2 + 11v + 3v^2 + 4v + 12$

Step2: Combine like $v^2$ terms

$8v^3 + (4v^2 + 3v^2) + 11v + 4v + 12 = 8v^3 + 7v^2 + 11v + 4v + 12$

Step3: Combine like $v$ terms

$8v^3 + 7v^2 + (11v + 4v) + 12 = 8v^3 + 7v^2 + 15v + 12$

Answer:

$8v^3 + 7v^2 + 15v + 12$
