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

Solution

simplify

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

Solution

\frac{2}{x + 2}

Solution steps

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

Factor

2 x - 4 : 2 (x - 2)

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

Factor

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

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

Cancel the common factor:

x - 2

= \frac{2}{x + 2}
