integral of (2x-5)/(x^2-5x+3)

\int \frac{2 x - 5}{x ^{2} - 5 x + 3} d x

ln x^{2} - 5 x + 3 + C

Solution steps

\int \frac{2 x - 5}{x ^{2} - 5 x + 3} 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} - 5 x + 3

= ln x^{2} - 5 x + 3

Add a constant to the solution

= ln x^{2} - 5 x + 3 + C

\int 12 x - 3 d x

\int (x + 2) d x

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

\int 3 tan (x) sec^{7} (x) d x

\int (x x - 8) d x
