integral of (x^2)/((x^3+2)^2)

\int \frac{x ^{2}}{( x ^{3} + 2 ) ^{2}} d x

- \frac{1}{3 ( x ^{3} + 2 )} + C

Solution steps

\int \frac{x ^{2}}{( x ^{3} + 2 ) ^{2}} d x

Apply u-substitution

: \int \frac{1}{3 u ^{2}} d u

= \int \frac{1}{3 u ^{2}} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{3} \cdot \int \frac{1}{u ^{2}} d u

Apply the Power Rule

: - \frac{1}{u}

= \frac{1}{3} (- \frac{1}{u})

Substitute back

u = x^{3} + 2

= \frac{1}{3} (- \frac{1}{x ^{3} + 2})

Simplify

\frac{1}{3} (- \frac{1}{x ^{3} + 2}) : - \frac{1}{3 ( x ^{3} + 2 )}

= - \frac{1}{3 ( x ^{3} + 2 )}

Add a constant to the solution

= - \frac{1}{3 ( x ^{3} + 2 )} + C

\frac{6 x}{x + 7}, at x = 1

\frac{\partial}{\partial y} (x e^{\frac{y}{x}})

x^{2} - 2

\int \frac{y ^{2} + 6 y + 9}{( y ^{2} + 9 ) ^{2}} d y

f (x) = 3 x - 1, at x = 5
