Question 85471
Multiply:
{{{((2x^2-x-3)/(3x^2+7x+4))((3x^2-11x-20)/(4x^2-9)))}}} It is often helpful to factor the numerators and the denominators, if possible, and cancel like-factors.
{{{((cross((2x-3))cross((x+1)))/(cross((3x+4))cross((x+1))))((cross((3x+4))highlight((x-5)))/(highlight((2x+3))cross((2x-3))))}}} Cancel like-factors as indicated, leaving you with:
{{{(x-5)/(2x+3)}}}
