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

expand

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

\frac{1}{s ^{3} - 3 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} - 3 s - 2

= \frac{1}{s ^{3} - 3 s - 2}

\frac{6 ( x + 2 )}{( x + 1 ) ( x + 3 ) ( x + 4 )}

\frac{s ^{2} + 2 s - k}{( s ^{2} + k ) ( s - k )}

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

3^{6}

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