expand (s^2+12)/((s^2+9)(s-1)(s+1)(s+2))

expand

\frac{s ^{2} + 12}{( s ^{2} + 9 ) ( s - 1 ) ( s + 1 ) ( s + 2 )}

\frac{s ^{2} + 12}{s ^{5} + 2 s ^{4} + 8 s ^{3} + 16 s ^{2} - 9 s - 18}

Solution steps

\frac{s ^{2} + 12}{( s ^{2} + 9 ) ( s - 1 ) ( s + 1 ) ( s + 2 )}

Expand

(s^{2} + 9) (s - 1) (s + 1) (s + 2) : s^{5} + 2 s^{4} + 8 s^{3} + 16 s^{2} - 9 s - 18

= \frac{s ^{2} + 12}{s ^{5} + 2 s ^{4} + 8 s ^{3} + 16 s ^{2} - 9 s - 18}

(3 x - 1)^{2} 3 x - 1

\frac{d + d ( 2 d - 7 )}{d}

\frac{( s ^{2} + 5 s + 10 )}{( s + 3 ) ( s + 2 ) ( s + 1 )}

(cos (t) - sin (t)) (- sin (t) - cos (t))

(ab + d c)^{2}
