expand 1/((s+1)^2(s+2))

expand

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

\frac{1}{s ^{3} + 4 s ^{2} + 5 s + 2}

Solution steps

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

(s + 1)^{2} = s^{2} + 2 s + 1

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

Expand

(s^{2} + 2 s + 1) (s + 2) : s^{3} + 4 s^{2} + 5 s + 2

= \frac{1}{s ^{3} + 4 s ^{2} + 5 s + 2}

\frac{d y}{( 2 y + 3 ) ^{2}}

\frac{x + 1}{x}

\frac{1}{s ( s ^{2} + 2 s + 5 )}

\frac{n ( n + 1 ) ( 2 n + 1 )}{3}

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