integral of (2x-3)/(x^2-3x+8)

\int \frac{2 x - 3}{x ^{2} - 3 x + 8} d x

ln x^{2} - 3 x + 8 + C

Solution steps

\int \frac{2 x - 3}{x ^{2} - 3 x + 8} 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} - 3 x + 8

= ln x^{2} - 3 x + 8

Add a constant to the solution

= ln x^{2} - 3 x + 8 + C

\int \frac{1 + ln ( x )}{( x ln ( x ) ) 2} d x

\int \frac{e ^{3 x}}{1 - e ^{3 x}} d x

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

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

\int 5 x cos (π x) d x
