expand 1/((s-1)^2(s-10)(s+2))

expand

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

\frac{1}{s ^{4} - 10 s ^{3} - 3 s ^{2} + 32 s - 20}

Solution steps

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

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

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

Expand

(s^{2} - 2 s + 1) (s - 10) (s + 2) : s^{4} - 10 s^{3} - 3 s^{2} + 32 s - 20

= \frac{1}{s ^{4} - 10 s ^{3} - 3 s ^{2} + 32 s - 20}

e^{y} \cdot (1 - e^{- 2 y})
