expand (s^3+2s^2+1)/(s^2(s^2+4))

expand

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

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

Solution steps

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

Expand

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

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

(5 + 32)^{2}

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

16 (\frac{1}{4} + \frac{7}{x ^{16}})

\frac{- 3 x ^{2} - 2 y}{2 ( x - 3 y )}
