expand (e^{-7s})/((s-3)(s-1))

expand

\frac{e ^{- 7 s}}{( s - 3 ) ( s - 1 )}

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

Solution steps

\frac{e ^{- 7 s}}{( s - 3 ) ( s - 1 )}

Expand

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

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

x (5 - x)

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

\frac{4}{s ( s ^{2} + 4 )}

- 2 (1 + 2 - 1)
