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

expand

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

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

Solution steps

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

Expand

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

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

\frac{x + 1}{5 x ( x + 3 )}

\frac{1}{z ( z ^{2} + 1 )}

\frac{e ^{- 4 x}}{( x + 3 ) ( x - 9 )}

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

\frac{( x - 1 ) ( x + 1 )}{( x + 5 ) ( x - 5 )}
