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

expand

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

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

Decimal Notation

- 0.20998 \dots

Solution steps

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

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

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

s (s^{2} + 5 s + 5)^{2}

\frac{1}{4 + 9 x ^{2}}

\frac{( 4 s + 5 )}{( ( s + 3 ) ( s - 4 ) ^{2} )}

(z^{2} + π^{2})^{2}

\frac{e ^{x} ( x - 3 )}{x ^{4}}
