expand ((e^{-3s})*(9-9s))/((s^2+4))

expand

\frac{( e ^{- 3 s} ) \cdot ( 9 - 9 s )}{( s ^{2} + 4 )}

\frac{9 e ^{- 3 s} - 9 e ^{- 3 s} s}{s ^{2} + 4}

Solution steps

\frac{( e ^{- 3 s} ) ( 9 - 9 s )}{s ^{2} + 4}

Remove parentheses:

(a) = a

= \frac{e ^{- 3 s} ( 9 - 9 s )}{s ^{2} + 4}

Expand

e^{- 3 s} (9 - 9 s) : 9 e^{- 3 s} - 9 e^{- 3 s} s

= \frac{9 e ^{- 3 s} - 9 e ^{- 3 s} s}{s ^{2} + 4}

\frac{1}{( x ^{2} + a ^{2} ) ^{3}}

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

\frac{( 2 x ) ^{3}}{3}

\frac{1}{s ( s + 1 ) ( s + 4 )}

\frac{K ( s + 2 )}{( s + 10 ) s ( s - 1 )}
