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

expand

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

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

Solution steps

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

Expand

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

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

\frac{5 x ^{2} - 2 x - 19}{( x + 3 ) ( x - 1 ) ^{2}}

\frac{s}{( s ^{2} + 49 ) ^{2}}

(2 + 3) (5 + 33)

\frac{3 x + 4}{( x + 2 ) ( x - 1 ) ^{2}}

45 + 4 y^{x + 2} - x^{2 (x + 2)}
