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

expand

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

- \frac{12 x}{x ^{4} + 6 x ^{2} + 9}

Solution steps

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

(x^{2} + 3)^{2} = x^{4} + 6 x^{2} + 9

= - \frac{12 x}{x ^{4} + 6 x ^{2} + 9}

(4 sin (θ) - 4 cos (θ))^{2}

6 (7 + 5)

(cos (x) cos (y) - cot (x)) d x

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

x - 5^{=} 10 (y + 6)
