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

expand

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

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

Solution steps

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

Expand

(x^{2} + x) (x^{2} + 1) : x^{4} + x^{2} + x^{3} + x

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

\frac{5 ( - 2 y + 3 )}{6}

(t - sin (t)) (sin (t))

6 (2^{\frac{1}{6}} - 1)

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

(4 x + y) (4 x - y)
