expand-(8(-3x^2-4))/((x^2-4)^3)

expand

- \frac{8 ( - 3 x ^{2} - 4 )}{( x ^{2} - 4 ) ^{3}}

- \frac{- 24 x ^{2} - 32}{x ^{6} - 12 x ^{4} + 48 x ^{2} - 64}

Solution steps

- \frac{8 ( - 3 x ^{2} - 4 )}{( x ^{2} - 4 ) ^{3}}

(x^{2} - 4)^{3} = x^{6} - 12 x^{4} + 48 x^{2} - 64

= - \frac{8 ( - 3 x ^{2} - 4 )}{x ^{6} - 12 x ^{4} + 48 x ^{2} - 64}

Expand

8 (- 3 x^{2} - 4) : - 24 x^{2} - 32

= - \frac{- 24 x ^{2} - 32}{x ^{6} - 12 x ^{4} + 48 x ^{2} - 64}

- 6 y l e f t (5 y^{2} - 4 y + 2)

\frac{x ^{2} + 1}{( x ^{3} - 5 x ^{2} - 6 x ) ( x ^{2} + x + 9 )}

(- 3 - i)^{5}

\frac{8 x ^{2} + 13}{( x ^{2} + 1 ) ( x + 1 )}

(e^{x} - 2) (e^{x} + 3)
