expand-(10(-x^2-12))/((x^2-4)^3)

expand

- \frac{10 ( - x ^{2} - 12 )}{( x ^{2} - 4 ) ^{3}}

- \frac{- 10 x ^{2} - 120}{x ^{6} - 12 x ^{4} + 48 x ^{2} - 64}

Solution steps

- \frac{10 ( - x ^{2} - 12 )}{( x ^{2} - 4 ) ^{3}}

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

= - \frac{10 ( - x ^{2} - 12 )}{x ^{6} - 12 x ^{4} + 48 x ^{2} - 64}

Expand

10 (- x^{2} - 12) : - 10 x^{2} - 120

= - \frac{- 10 x ^{2} - 120}{x ^{6} - 12 x ^{4} + 48 x ^{2} - 64}

\frac{x}{1400} (x - 0.028 = 15)

\frac{d x}{( x + 1 ) ( x ^{2} + 1 )}

r^{2} (1 + 3 cos (2) (θ))

\frac{( x + y )}{4 ( 1 - x ) ( 1 - x - y )}

\frac{k s}{( s ^{2} + 20 s + 200 ) ( s + a )}
