expand-(2s(-s^2-27))/((s^2-9)^3)

expand

- \frac{2 s ( - s ^{2} - 27 )}{( s ^{2} - 9 ) ^{3}}

- \frac{- 2 s ^{3} - 54 s}{s ^{6} - 27 s ^{4} + 243 s ^{2} - 729}

Solution steps

- \frac{2 s ( - s ^{2} - 27 )}{( s ^{2} - 9 ) ^{3}}

(s^{2} - 9)^{3} = s^{6} - 27 s^{4} + 243 s^{2} - 729

= - \frac{2 s ( - s ^{2} - 27 )}{s ^{6} - 27 s ^{4} + 243 s ^{2} - 729}

Expand

2 s (- s^{2} - 27) : - 2 s^{3} - 54 s

= - \frac{- 2 s ^{3} - 54 s}{s ^{6} - 27 s ^{4} + 243 s ^{2} - 729}

2 (\frac{x ^{2}}{2} + t^{2} + t = c)
