simplify (x^2+2x)/(x^2-4)

Solution

simplify

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

Solution

\frac{x}{x - 2}

Solution steps

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

Factor

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

= \frac{x ( x + 2 )}{x ^{2} - 4}

Factor

x^{2} - 4 : (x + 2) (x - 2)

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

Cancel the common factor:

x + 2

= \frac{x}{x - 2}
