integral of (2x+3)/(x^2+3x-10)

\int \frac{2 x + 3}{x ^{2} + 3 x - 10} d x

ln x^{2} + 3 x - 10 + C

Solution steps

\int \frac{2 x + 3}{x ^{2} + 3 x - 10} d x

Apply u-substitution

= \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} + 3 x - 10

= ln x^{2} + 3 x - 10

Add a constant to the solution

= ln x^{2} + 3 x - 10 + C
