what is (x to the 3rd power + x to the 2nd power) divided by ((x+4)(X-4)) multiplied by (x+4) divided by (3x to the 4th power + x to the 3rd power + 2x to the 2nd power)
Is this what you like simplified?
(x³ + x²)/((x+4)(x-4)) * (x+4)/(3x4 + x³ + 2x²)
Cancel the common factor (x+4).
The second denominator can be factored into x²(3x²+x+2)
