integral of (x^2)/(x^3+10)

\int \frac{x ^{2}}{x ^{3} + 10} d x

\frac{1}{3} ln x^{3} + 10 + C

Solution steps

\int \frac{x ^{2}}{x ^{3} + 10} d x

Apply u-substitution

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

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{3} ln ∣ u ∣

Substitute back

u = x^{3} + 10

= \frac{1}{3} ln x^{3} + 10

Add a constant to the solution

= \frac{1}{3} ln x^{3} + 10 + C
