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

expand

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

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

Solution steps

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

Expand

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

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

8 (- 0.4 e^{- 0.4 t} + 0.6 e^{- 0.6 t})

\frac{( x - 4 ) x}{2 x + 8}

d x (1 + \frac{1}{x})

\frac{x + 2}{( x - 1 ) ( x ^{2} + 4 )}

\frac{( x ^{3} - x ^{2} - 2 x ) ( 2 x ^{2} + 6 x + 7 )}{( x + 2 )}
