expand (e^{-x})/((1+e^{-x))^2}

expand

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

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

Solution steps

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

(1 + e^{- x})^{2} = 1 + 2 e^{- x} + e^{- 2 x}

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

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

- 211 (4 + 37)

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

(e^{x} + 1) (e^{x} - 1)

(x - \frac{24}{x + 2}) (x - \frac{12}{x - 4})
