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

expand

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

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

Solution steps

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

Expand

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

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

\frac{( x + 2 ) ( x - 3 )}{x - 1}

B (2 x (3 x - 7))

\frac{5 x - 35}{7 ( x + 3 )}

\frac{16 x + 16}{s ( s + 2 ) ( s + 4 )}

- (e^{x} (x - 1))
