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 (\frac{2}{x ^{2}} + \frac{3}{x ^{4}}) d x

\int \frac{1}{8 + 4 x - 4 x ^{2}} d x

\int e^{- 7 x} sin (2 x) d x

\int e^{2 z} cos (\frac{1}{4} z) d z

\int \frac{1}{x} cos (\frac{1}{x}) d x
