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

expand

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

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

Solution steps

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

Expand

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

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

\frac{1}{s ( a + s )}

(- x)^{2}

\frac{x ^{3} - 1}{x ^{2} ( x - 2 ) ^{3}}

(x - e)^{2}

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