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

expand

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

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

Solution steps

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

Expand

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

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