Question

How to simplify this expression

Answer 1

$\frac{2x+4}{3x-3}( \frac{12x-12}{x+5})$
=$\frac{2(x+2)}{3(x-1)}( \frac{12(x-1)}{x+5})$
=$\frac{2(x+2)4}{x+5}$
=$\frac{8(x+2)}{x+5}$

--------------------------------------
$\frac{x^2-16}{2x-8}$÷ $\frac{x-4)^2}{8x-32}$
=$\frac{x^2-16}{2x-8}$( $\frac{8x-32}{x-4)^2}$)
=$\frac{(x-4)^2}{2x-8}$( $\frac{8x-32}{x-4)^2}$)
=$\frac{1}{2x-8}$( $\frac{8x-32}{1}$)
=$\frac{8x-32}{2x-8}$
=$\frac{8(x-4)}{2(x-4)}$
=$\frac{4(x-4)}{1(x-4)}$
