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

expand

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

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

Solution steps

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

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

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

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

(sec (θ) + tan (θ))^{2}

(2 - y i)^{2}

(3 x - 2 i)^{2}

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