Question 65475
Multiply the fraction and put in simplest form:

2x^2-x-3  *  3x^2-11x-20
------------------------
3x^2+7x+4 *  4x^2-9


================================================

Factor and re-write as follows:

=[(2x-3)(x+1)*(x-5)(3x+4)]/[(x+1)(x+4)*(2x-3)(2x+3)]

Cancel where you can to get:

=[(x-5)(3x+4)]/[(x+4)(2x+3)]
