expand (-3s^2+9s+18)/((s^2-4)(s-3)(s+1))

expand

\frac{- 3 s ^{2} + 9 s + 18}{( s ^{2} - 4 ) ( s - 3 ) ( s + 1 )}

\frac{- 3 s ^{2} + 9 s + 18}{s ^{4} - 2 s ^{3} - 7 s ^{2} + 8 s + 12}

Solution steps

\frac{- 3 s ^{2} + 9 s + 18}{( s ^{2} - 4 ) ( s - 3 ) ( s + 1 )}

Expand

(s^{2} - 4) (s - 3) (s + 1) : s^{4} - 2 s^{3} - 7 s^{2} + 8 s + 12

= \frac{- 3 s ^{2} + 9 s + 18}{s ^{4} - 2 s ^{3} - 7 s ^{2} + 8 s + 12}
