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

expand

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

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

Solution steps

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

Expand

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

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

(2 x^{2} + 3 x - 4) - (x^{2} + x = 8)

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

(2 + \frac{8}{5} x)^{8}

\frac{x ^{3}}{x}

(n + 1)! \cdot (n + 2)
