Question

What is the product?

Answer 1

Answer:

A

Step-by-step explanation:

Factor out each equation

(x+4)(x-4)/2(x+4)  x(x-1)(x-1)/(x-1)(x+4)

cancel out the similar ones.

leaving you with x(x-4)(x-1)/2(x+4)

Answer 2

Answer:

$\frac{x(x-4)(x-1)}{2(x+4)}$

Step-by-step explanation:

$\frac{(x-4)(x+4)x(x^{2}-2x+1) }{2(x+4)(x^{2}+4x-1x-4) } \\= \frac{(x-4)x(x-1)^{2} }{2(x(x+4)-1(x+4))}\\= \frac{(x-4)x(x-1)^{2} }{2(x+4)(x-1)}\\ = \frac{x(x-4)(x-1)}{2(x+4)}$

Cancelled (x+4) in the numerator and denominator to arrive at the 2nd step.

Cancelled (x-1) in the numerator and denominator to arrive at the answer.
