expand 1/((s+4)(s^2+1))

expand

\frac{1}{( s + 4 ) ( s ^{2} + 1 )}

\frac{1}{s ^{3} + s + 4 s ^{2} + 4}

Solution steps

\frac{1}{( s + 4 ) ( s ^{2} + 1 )}

Expand

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

= \frac{1}{s ^{3} + s + 4 s ^{2} + 4}

\frac{2 x ^{3} + 4 x ^{2} - 14 x}{( x - 4 ) ( x + 2 )}

\frac{\partial}{\partial y} ((u) (C y (2 h - y)))

\frac{( 4 - x ) ^{3}}{64}

(- x^{(2)} + 3 x + 1) d x

\frac{5 x}{2 ( x - 3 )}
