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

simplify

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

\frac{3 x}{x - 3}

Solution steps

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

Factor

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

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

Factor

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

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

Cancel the common factor:

x + 3

= \frac{3 x}{x - 3}

\frac{e ^{- 2} \cdot 2 ^{0}}{0 !}

6 (- 5)

\frac{x ^{2} - x y + 4 x - 4 y}{x ^{2} - 2 x y + y ^{2}}

\frac{2 π}{\frac{5}{6}}

\frac{x ^{2} + 4 x - 12}{x ^{2} ( x ^{2} + 9 x + 18 )} \cdot 6 x^{2}
