integral of x/(x^2-x)

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

ln ∣ x - 1 ∣ + C

Solution steps

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

Factor

\frac{x}{x ^{2} - x}

= \int \frac{x}{x ( x - 1 )} d x

Apply u-substitution

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

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

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= ln ∣ u ∣

Substitute back

u = x - 1

= ln ∣ x - 1 ∣

Add a constant to the solution

= ln ∣ x - 1 ∣ + C

\int \frac{e ^{2 x + 1}}{e ^{2 x} + 3} d x

\int \frac{x - 2}{x + 1} d x

\int (3 x^{2} + 8 x - 4) d x

\int \frac{1}{( 1 - x ^{2} ) arcsin ( x )} d x

\int \frac{e ^{6 x}}{e ^{6 x} + 2} d x
