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

expand

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

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

Solution steps

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

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

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

e^{2 (2 x + l n (2))}

\frac{( 3 ln ( x ) - 5 ) ^{4}}{x}

y + 0

3 x (1 - x^{2})^{3} d x

(x^{2} + 1)^{2} x e^{2 x}
