Question

add.
$(3v^{2} - 9v + 1) + (4v + 7)$

Explanation:

Step1: Remove parentheses

$3v^2 - 9v + 1 + 4v + 7$

Step2: Combine like terms

For the \(v\) terms: \(-9v + 4v = -5v\)
For the constant terms: \(1 + 7 = 8\)
The \(3v^2\) term remains as is.
So we get \(3v^2 - 5v + 8\)

Answer:

\(3v^2 - 5v + 8\)
