Question 748833: Its been WAY too long since I did algebra. Trying to help my son with an equation but I just cannot remember how this stuff works...
what is the simplest form of x+3 over x3-x2-6x divided by x2-9 over x2+x-12?
Little help, please?

what is the simplest form of:
%28%28x%2B3%29%29%2F%28%28x%5E3-x%5E2-6x%29%29
-------------
%28%28x%5E2-9%29%29%2F%28%28x%5E2%2Bx-12%29%29
:
Remember when you divide fractions, invert the dividing fraction and Multiply
%28%28x%2B3%29%29%2F%28%28x%5E3-x%5E2-6x%29%29 * %28%28x%5E2%2Bx-12%29%29%2F%28%28x%5E2-9%29%29
:
Factor as much as we can
%28%28x%2B3%29%29%2F%28x%28x%5E2-x-6%29%29 * %28%28x%2B4%29%28x-3%29%29%2F%28%28x-3%29%28x%2B3%29%29
:
the first denominator can be factored again
%28%28x%2B3%29%29%2F%28x%28x-3%29%28x%2B2%29%29 * %28%28x%2B4%29%28x-3%29%29%2F%28%28x-3%29%28x%2B3%29%29
:
Cancel x+3 and x-3, in the 2nd denominator
1%2F%28x%28x-3%29%28x%2B2%29%29 * (x+4) = %28%28x%2B4%29%29%2F%28x%28x-3%29%28x%2B2%29%29; about all you can do with it.
