expand (1+s^2)/(s^2(s-4)^2)

expand

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

\frac{1 + s ^{2}}{s ^{4} - 8 s ^{3} + 16 s ^{2}}

Solution steps

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

(s - 4)^{2} = s^{2} - 8 s + 16

= \frac{1 + s ^{2}}{s ^{2} ( s ^{2} - 8 s + 16 )}

Expand

s^{2} (s^{2} - 8 s + 16) : s^{4} - 8 s^{3} + 16 s^{2}

= \frac{1 + s ^{2}}{s ^{4} - 8 s ^{3} + 16 s ^{2}}
