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

expand

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

\frac{2 x}{x ^{4} - 2 x ^{2} + 1}

Solution steps

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

(x^{2} - 1)^{2} = x^{4} - 2 x^{2} + 1

= \frac{2 x}{x ^{4} - 2 x ^{2} + 1}

\frac{d}{d x} ((f (x)) (6 x^{3} - 5))

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

- \frac{2 x ^{2} + 13 x - 12}{( x ^{2} + 6 ) ( x + 2 )}

ln (7 \cdot x^{9} y^{2})

(e^{3 t} - 1)^{2}
