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

Solution

simplify

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

Solution

\frac{x - 3}{x}

Solution steps

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

Factor

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

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

Factor

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

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

Cancel the common factor:

x + 3

= \frac{x - 3}{x}
