I'm going to assume your problem is this:
(a^2-9)/a^2 * (a^2-3a)/(a^2+a-12)
Note: I'm using * to mean multiply.
If that is the problem, then you want to try to factor first, so you can reduce wherever you can.
(a+3)(a-3)/a^2 * a(a-3)/(a+4)(a-3)
Cancel out (a-3) in both the numerator and denominator of the second fraction to end up with this:
(a+3)(a-3)/a^2 * a/(a+4)
We can still reduce a/a^2 to end up with this:
And that's about as far as we can go on this one!
I hope this helps and is what you were asking for this problem.
