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

expand

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

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

Solution steps

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

Expand

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

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

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

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

(2 x - 3) e^{3}

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

\frac{d ^{2}}{d x ^{2}} ((y) (y^{4} - 2 x - 5))
