a^2-9 a^2-3a

----- * -------

a^2 a^2+a-12

*I got:

3-3a/4

I don't think so.

factor the a^2-9, and the second numerator to a(a-3)

Then the denominator factored is

a^2*(a+4)(a-3)

So wait...

don't I have to first have to take out the repeated thingys.?

I don't know what repeated things means. Factor the numerator, and the denominator. Divide out common terms, and reduce. Ohhhh. on the second numerator, you can factor out an a, as I showed above.

I mean take out the common terms...sorry
