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

expand

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

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

Solution steps

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

Expand

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

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

\frac{8 r + 18}{( r + 3 ) ( 9 r - 28 )}

- 30 x + 780 (1 - e^{- \frac{x}{3}})

t^{\frac{7}{2}} (t^{2} - 4 t + 23)

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