Simplify x2−1x3+2x2−x−2

Question 1 Report

Simplify $\frac{x^{2} - 1}{x^{3} + 2 x^{2} - x - 2}$

\frac{1}{x + 2}

\frac{x - 1}{x + 1}

\frac{x - 1}{x + 2}

x−1x+2

\frac{1}{x - 2}

Answer Details

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

= $\frac{1}{x + 2}$
