integral of x/(6x^2-4)

\int \frac{x}{6 x ^{2} - 4} d x

\frac{1}{12} ln 6 x^{2} - 4 + C

Solution steps

\int \frac{x}{6 x ^{2} - 4} d x

Apply u-substitution

: \int \frac{1}{12 u} d u

= \int \frac{1}{12 u} d u

Take the constant out:

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

= \frac{1}{12} \cdot \int \frac{1}{u} d u

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{12} ln ∣ u ∣

Substitute back

u = 6 x^{2} - 4

= \frac{1}{12} ln 6 x^{2} - 4

Add a constant to the solution

= \frac{1}{12} ln 6 x^{2} - 4 + C

\int (2 t + 2) d t

\int \frac{5}{4} x^{3} d x

sec^{5} (x) tan (x)

\int x csc (4 x^{2}) d x

\int \frac{7}{25 x ^{2} + 36} d x
