expand (5s^2-s-2)/((s+2)(s^2+1))

expand

\frac{5 s ^{2} - s - 2}{( s + 2 ) ( s ^{2} + 1 )}

\frac{5 s ^{2} - s - 2}{s ^{3} + s + 2 s ^{2} + 2}

Solution steps

\frac{5 s ^{2} - s - 2}{( s + 2 ) ( s ^{2} + 1 )}

Expand

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

= \frac{5 s ^{2} - s - 2}{s ^{3} + s + 2 s ^{2} + 2}

(cos (θ) + i sin (θ))^{5}

\frac{b}{s ^{2} ( s + a )}

\frac{s}{( s ^{2} + 9 ) ^{2}}

cos (\frac{( 2 n - 1 ) π}{2})

(\frac{x}{2 - 5 y})^{4}
