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

expand

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

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

Solution steps

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

Expand

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

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

Expand

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

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

(L^{\frac{1}{3}} + K^{\frac{1}{3}})^{3}

(1 + cos (x))^{3}

(2 x^{3} + 8) (3 12 - 5 x)

(cos (x) + y sin (x))^{2}
