Let (just so it's easier to visualize).
So the problem becomes:
Is this something you could factor ?
so I was doing my homework today and I stumbled upon this problem, I had no trouble with any of the other ones and I look at the problem and I have no idea what to do.
problem:
factor problem using the greatest common binomial factor.
3a(a+b)-(a+b)
so is it just.
(3a)(-1)(a+b)
or
3a(a-b)^2
haha, I'm sure this problem is really easy, I don't know why I have no idea how to do it.
