4v^2-12v+2

Explanation:

Combining like terms means adding together the terms with the same power on the variable.

We can rearrange your equation as:
1v^2 - 5v - 2 + 3v^2 - 7v +4

1v^2 + 3v^2 - 5v - 7v - 2 +4

Now we can add the like terms, so the v^2 term will be 1+3 and so on:

(1+3)v^2 + (-5-7)v + (-2+4)

Giving the solution
