expand (8x)/((x^2+1)^2)

expand

\frac{8 x}{( x ^{2} + 1 ) ^{2}}

\frac{8 x}{x ^{4} + 2 x ^{2} + 1}

Solution steps

\frac{8 x}{( x ^{2} + 1 ) ^{2}}

(x^{2} + 1)^{2} = x^{4} + 2 x^{2} + 1

= \frac{8 x}{x ^{4} + 2 x ^{2} + 1}

\frac{( x - 5 ) ( x + 4 )}{x ^{2} + x + 30}

\frac{d x}{x ( x ^{2} + 5 )}

\frac{6 x ^{3} - 5 x ^{2}}{( x ^{2} - 3 ) ^{2}}

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

- \frac{2 ( 4 + 6 )}{5}
