expand 1/(s(s+1)^3)

Solution

expand

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

Solution

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

Solution steps

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

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

= \frac{1}{s ( s ^{3} + 3 s ^{2} + 3 s + 1 )}

Expand

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

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