expand-4/((s+2)(s^2+4s+8))

expand

- \frac{4}{( s + 2 ) ( s ^{2} + 4 s + 8 )}

- \frac{4}{s ^{3} + 6 s ^{2} + 16 s + 16}

Solution steps

- \frac{4}{( s + 2 ) ( s ^{2} + 4 s + 8 )}

Expand

(s + 2) (s^{2} + 4 s + 8) : s^{3} + 6 s^{2} + 16 s + 16

= - \frac{4}{s ^{3} + 6 s ^{2} + 16 s + 16}

(x + 4 - 2) (x - 4 + 2)

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

(x + 4) (x - 4)

\frac{4 e ^{- 2 s} - 4}{s ( s + 2 )}
