integral of (x^2-2)/(x^3-6x+2)

\int \frac{x ^{2} - 2}{x ^{3} - 6 x + 2} d x

\frac{1}{3} ln x^{3} - 6 x + 2 + C

Solution steps

\int \frac{x ^{2} - 2}{x ^{3} - 6 x + 2} d x

Apply u-substitution

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

= \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} - 6 x + 2

= \frac{1}{3} ln x^{3} - 6 x + 2

Add a constant to the solution

= \frac{1}{3} ln x^{3} - 6 x + 2 + C

\int x 3 + 2 x d x

\int (x + 7) e^{0.1 x + 2} d x

\int (e^{- 5 x} + 7^{x}) d x

\int \frac{5}{3 sin ( x ) - 4 cos ( x )} d x

\int \frac{9 x ( 6 x ^{2} + 1 ) ^{2}}{2} d x
