expand-(144(-x^2+4))/((x^2+12)^3)

expand

- \frac{144 ( - x ^{2} + 4 )}{( x ^{2} + 12 ) ^{3}}

- \frac{- 144 x ^{2} + 576}{x ^{6} + 36 x ^{4} + 432 x ^{2} + 1728}

Solution steps

- \frac{144 ( - x ^{2} + 4 )}{( x ^{2} + 12 ) ^{3}}

(x^{2} + 12)^{3} = x^{6} + 36 x^{4} + 432 x^{2} + 1728

= - \frac{144 ( - x ^{2} + 4 )}{x ^{6} + 36 x ^{4} + 432 x ^{2} + 1728}

Expand

144 (- x^{2} + 4) : - 144 x^{2} + 576

= - \frac{- 144 x ^{2} + 576}{x ^{6} + 36 x ^{4} + 432 x ^{2} + 1728}
