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

expand

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

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

Solution steps

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

Expand

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

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

\frac{x ^{2}}{( cos ( x ) + x sin ( x ) ) ^{2}}

\frac{10 x ^{2} + 50 x}{( 2 x + 5 ) ^{2}}

1.3 (1 + e^{0, 4 \cdot \frac{3}{7}})

\frac{( x + 3 )}{( x ^{2} + 2 x + 2 ) ( x ^{3} + 10 x ^{2} + 29 x + 20 )}

\frac{5 + 4 x - 3 x ^{2}}{( 1 - 2 x ) ( 2 + x ) ^{2}}
