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

expand

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

(3 - 0.1 e^{x})^{2}

\frac{2 x ^{2} - 15}{x ( x + 3 )}

(4 + e) 2

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