expand (x^3)/((x^2+1)(x^4-x^2+1))

expand

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

\frac{x ^{3}}{x ^{6} + 1}

Solution steps

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

Expand

(x^{2} + 1) (x^{4} - x^{2} + 1) : x^{6} + 1

= \frac{x ^{3}}{x ^{6} + 1}

\frac{1}{a s ^{2}} - \frac{e ^{- a s}}{s ( 1 - e ^{- a s} )}

\frac{( a + b - 2 ab ) ( a + b )}{a - b}

\frac{x ( x + 1 )}{x + 4}

(a - b) (a - c) (a - d) (a - e)

\frac{( 6 k + 3 ) x ^{2} - k x - 1}{3 x - 1}
