Concentrate on (9r^2 + 6r - 24), simplify and factor if possible:
3(3r^2 + 2r - 8) can be further factored to: 3(3x - 4)(x + 2), factoring the others is pretty easy, you will have:
:
*

Can do some major cancelling here: 3 into 6, 4 into 4, leaving us with:
*
:
you know that you can cancel across the "*" so you can cancel (r-3) & (3r-4):
is what's left
:
Usually when they give you these problems, a lot of factoring can be done, so look for that first.
