expand 1/(s(as+1)(bs+1))

expand

\frac{1}{s ( a s + 1 ) ( b s + 1 )}

\frac{1}{ab s ^{3} + a s ^{2} + b s ^{2} + s}

Solution steps

\frac{1}{s ( a s + 1 ) ( b s + 1 )}

Expand

s (a s + 1) (b s + 1) : ab s^{3} + a s^{2} + b s^{2} + s

= \frac{1}{ab s ^{3} + a s ^{2} + b s ^{2} + s}

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

\frac{1 - e ^{- s}}{s \cdot ( s ^{2} + 2 s + 26 )}

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

(tan^{2} (12 x) - cot^{2} (12 x))^{2}

(e^{y} - e^{- y})^{2}
