10-87.

Multiply or divide the expressions below. Leave your answer as simplified as possible.

For additional help with fractional expressions, see problem 10-65.

1. $\frac{8x^2-12x-8}{2x^2-5x-3}\cdot\frac{x^2+2x-15}{6x-12}$

$\frac{4(2x+1)(x-2)}{(x-3)(2x+1)}\cdot\frac{(x-3)(x+5)}{6(x-2)}$

This simplifies to the following:

$\frac{4(x+5)}{6}=\frac{2(x+5)}{3}$

$\frac{ 2(x + 5) }{3 }$

1. $\frac{7x^2+5x-2}{x^2+2x-8}\div\frac{3x^2-2x-5}{3x^2-11x+10}$

$\frac{(7x-2)}{(x+4)}$
