expand (3s+e^{-s+1}+9)/((s-1)(s+2))

expand

\frac{3 s + e ^{- s + 1} + 9}{( s - 1 ) ( s + 2 )}

\frac{3 s + e ^{- s + 1} + 9}{s ^{2} + s - 2}

Solution steps

\frac{3 s + e ^{- s + 1} + 9}{( s - 1 ) ( s + 2 )}

Expand

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

= \frac{3 s + e ^{- s + 1} + 9}{s ^{2} + s - 2}

(x - 4 i) (x + 4 i)

N e^{i x} (2 e^{i x} + 1)

\frac{( 2 x ^{2} ) ( 0.9 + 2 x ^{2} )}{( 1.3 - x ) ( 2.15 - 4 x ) ^{4}}
