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}

- 5 r^{2} sin (θ) (r^{2} - 9)

\frac{3}{n ( n + 3 )}

(4 a - b) (3 a + 2 b)

\frac{2 x + 1}{x ( x + 1 )}

(x - 1)^{2} + y^{2}
