expand 1/(s^2)-(e^{-s})/(s(1-e^{-s))}

expand

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

\frac{1}{s ^{2}} - \frac{e ^{- s}}{s - e ^{- s} s}

Solution steps

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

Expand

s (1 - e^{- s}) : s - e^{- s} s

= \frac{1}{s ^{2}} - \frac{e ^{- s}}{s - e ^{- s} s}

(x + 10) (x - 10)

(1 + e^{t})^{2}

\frac{1}{( 2 - 5 x ) ^{2}}

\frac{( 18 e ^{x} )}{( 3 e ^{x} + 6 ) ^{2}}
