expand (4x)/((x-1)^2(x+1))

expand

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

\frac{4 x}{x ^{3} - x ^{2} - x + 1}

Solution steps

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

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

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

Expand

(x^{2} - 2 x + 1) (x + 1) : x^{3} - x^{2} - x + 1

= \frac{4 x}{x ^{3} - x ^{2} - x + 1}

\frac{d}{d x} ((5) (x^{4} - \frac{10}{x}))

- \frac{t ( 1 + in )}{d t}

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

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

- \frac{d}{d s} (\frac{e ^{- π s}}{s ( s ^{2} + 1 )})
