expand (2x)/((x+1)(x-1))

expand

\frac{2 x}{( x + 1 ) ( x - 1 )}

\frac{2 x}{x ^{2} - 1}

Solution steps

\frac{2 x}{( x + 1 ) ( x - 1 )}

Expand

(x + 1) (x - 1) : x^{2} - 1

= \frac{2 x}{x ^{2} - 1}

(x - 2 x + 1)^{2}

A (- 2, - 3) y B (5, 1)

\frac{3 x ^{2} + x + 2}{x ^{2} ( x ^{2} + 4 )}

\frac{( x + 1 ) ( 2 x - 1 )}{x + 2}

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