expand (4x)/((x^2+2)^2)

expand

\frac{4 x}{( x ^{2} + 2 ) ^{2}}

\frac{4 x}{x ^{4} + 4 x ^{2} + 4}

Solution steps

\frac{4 x}{( x ^{2} + 2 ) ^{2}}

(x^{2} + 2)^{2} = x^{4} + 4 x^{2} + 4

= \frac{4 x}{x ^{4} + 4 x ^{2} + 4}

(tan (x) + sin (x)) cot (x) - cos (x)

(x - 23) (x + 23)

(16 x^{2} + 5 x + 8)^{5}

(3 d^{4} - 7 e^{3})^{2}

\frac{cos ( x )}{( tan ( x ) ) ( 1 - sin ( x ) )}
