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

simplify

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

x + 3

Solution steps

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

Factor

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

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

Factor

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

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

Cancel the common factor:

x

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

Cancel the common factor:

x - 3

= x + 3

\frac{3 - 2 i}{2 i}

\frac{1. 1 ^{4} - 1}{1. 1 ^{6} - 1}

5 + 2 (3 x - 4) - x
