Answer:
3v^2 - 3v + 9
Step-by-step explanation:
Combine like terms
6v^2 and -3v^2 are like terms the variables are the same so you can combine them to get
6v^2 - 3v^2 = 3v^2
-4v and v are like terms so you can combine them
-4v + v = -3v
Last like terms 2 and 7
2+7=9
Now that you simplified all like terms recombine them.
3v^2 - 3v + 9
