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

expand

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

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

Solution steps

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

Expand

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

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

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

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

\frac{x ^{2} ( 8 y ^{3} + 3 x ) ^{2}}{16}

\frac{1}{( s ^{2} + a ^{2} ) \cdot ( s ^{2} + b ^{2} )}

\frac{d ^{2}}{d y ^{2}} ((f (x)) (x (y - sin (y))))
