expand (1-e^{-s})/(s(s^2+3s+2))

expand

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

\frac{1 - e ^{- s}}{s ^{3} + 3 s ^{2} + 2 s}

Solution steps

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

Expand

s (s^{2} + 3 s + 2) : s^{3} + 3 s^{2} + 2 s

= \frac{1 - e ^{- s}}{s ^{3} + 3 s ^{2} + 2 s}

(x + 3 - 2 i) (x + 3 + 2 i)

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

\frac{π + π e ^{- s}}{( s ^{2} + 4 ) ( s ^{2} + π ^{2} )}

(3 - x - 1)^{2}
