You can put this solution on YOUR website!
The GCF is the Greatest Common Factor
So when you take out the GCF, it means you want to take out the biggest thing that you can divide both numbers by
So ask yourself, what is the largest number i can take out of both of these numbers?
You should come up with 3x, because you can take 3x evenly out of both 3x and 9x%5E3
So the answer is 3x%281-3x%5E2%29 or choice B
