(24x^3)/(4x^2-36) * (2x^2+6x)/(16x^2)
-----------------------
Factor where possible:
(24x^3)/(4(x-3)(x+3)) * (2x(x+3))/(16x^2)
--------------------------
Cancel factors common to a numerator and a denominator,
such as 8, x^2, (x+3)
----------------------------
= (3x)/((x-3)) * (x/(8))
= (3x^2/(8(x-3))
