integral of (2x-1)/(x^2-x+1)

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

ln x^{2} - x + 1 + C

Solution steps

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

= ln x^{2} - x + 1

Add a constant to the solution

= ln x^{2} - x + 1 + C

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

\int x^{15} sin (x^{16}) d x

\int \frac{1}{2 ( x ^{\frac{1}{3}} )} d x

\int x^{2} sin (2 x^{3}) d x

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