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

Solution

simplify

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

Solution

\frac{x}{x + 3}

Solution steps

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

Factor

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

= \frac{x ( x - 3 )}{x ^{2} - 9}

Factor

x^{2} - 9 : (x + 3) (x - 3)

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

Cancel the common factor:

x - 3

= \frac{x}{x + 3}
