expand (e^{-5s}-e^{-3s}+7s+18)/((s-4)(s+1))

expand

\frac{e ^{- 5 s} - e ^{- 3 s} + 7 s + 18}{( s - 4 ) ( s + 1 )}

\frac{e ^{- 5 s} - e ^{- 3 s} + 7 s + 18}{s ^{2} - 3 s - 4}

Solution steps

\frac{e ^{- 5 s} - e ^{- 3 s} + 7 s + 18}{( s - 4 ) ( s + 1 )}

Expand

(s - 4) (s + 1) : s^{2} - 3 s - 4

= \frac{e ^{- 5 s} - e ^{- 3 s} + 7 s + 18}{s ^{2} - 3 s - 4}

\frac{( x ( x + 1 ) )}{2} + \frac{1}{4} - C e^{2 x}

\frac{3 ( x + 4 )}{x ^{2} + 7 x}

- 12 (\frac{x}{48} - \frac{y}{24})

\frac{3}{( x ^{2} + 9 ) ( x - 12 )}

\frac{d}{d u} ((x) (x + 1))
