expand-(e^x)/((c+e^x)^2)

expand

- \frac{e ^{x}}{( c + e ^{x} ) ^{2}}

- \frac{e ^{x}}{c ^{2} + 2 c e ^{x} + e ^{2 x}}

Solution steps

- \frac{e ^{x}}{( c + e ^{x} ) ^{2}}

(c + e^{x})^{2} = c^{2} + 2 c e^{x} + e^{2 x}

= - \frac{e ^{x}}{2 c e ^{x} + e ^{2 x} + c ^{2}}

, (5 x - 8 q^{2}) (2 (m - 2))

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

\frac{4 x ^{2} - 8 x + 1}{( x + 2 ) ( x ^{2} - 2 x + 3 )}

π (2 ln (3) + \frac{2}{3})

\frac{- 4 x ^{2} - 10 x - 4}{( x ^{2} - 1 ) ^{2}}
