simplify (x^3-9x)/(x^2-2x-3)

simplify

\frac{x ^{3} - 9 x}{x ^{2} - 2 x - 3}

\frac{x ( x + 3 )}{x + 1}

Solution steps

\frac{x ^{3} - 9 x}{x ^{2} - 2 x - 3}

Factor

x^{3} - 9 x : x (x + 3) (x - 3)

= \frac{x ( x + 3 ) ( x - 3 )}{x ^{2} - 2 x - 3}

Factor

x^{2} - 2 x - 3 : (x + 1) (x - 3)

= \frac{x ( x + 3 ) ( x - 3 )}{( x + 1 ) ( x - 3 )}

Cancel the common factor:

x - 3

= \frac{x ( x + 3 )}{x + 1}

0.85 - \frac{1}{2}

(x - 5) - (x^{2} - 1)

(- 10 x)^{- 2}

3 x \cdot 6 x

3 x \cdot 7 x
