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

expand

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

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

Solution steps

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

Expand

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

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

x (x + 1 - x)

(2 + 3) (6 - 2)

\frac{d}{d θ} ((x (θ)) (θ - sin (θ)))

(e^{x} sin (2 x)) (e^{x} cos (2 x) - 2 e^{x} sin (2 x))

- 2 (4 e^{- x^{2}} x^{3} - 6 e^{- x^{2}} x)
