#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
