expand (8e^{-pis})/((s^2+1)(s^2+9))

expand

\frac{8 e ^{- π s}}{( s ^{2} + 1 ) ( s ^{2} + 9 )}

\frac{8 e ^{- π s}}{s ^{4} + 10 s ^{2} + 9}

Solution steps

\frac{8 e ^{- π s}}{( s ^{2} + 1 ) ( s ^{2} + 9 )}

Expand

(s^{2} + 1) (s^{2} + 9) : s^{4} + 10 s^{2} + 9

= \frac{8 e ^{- π s}}{s ^{4} + 10 s ^{2} + 9}

\frac{1}{1 + x ^{4}}

5 (2 d + 6 ec + 6 a)

(1 - e^{x}) (1 + e^{x})

[ln^{2} (1 + x) \cdot (1 + x)]^{^{'}}

\frac{( e ^{- s} + s )}{s ( s - 5 ) ( s - 6 )}
