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

expand

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

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

Solution steps

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

Expand

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

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

(sec (θ) + tan (θ))^{2}

(2 - y i)^{2}

(3 x - 2 i)^{2}

x^{\frac{2}{3}} (x - 5)

\frac{1}{2} (x - \frac{1}{2} sin (2 x))
