integral of (x^2-5x+9)/(x^2-5x+6)

\int \frac{x ^{2} - 5 x + 9}{x ^{2} - 5 x + 6} d x

3 (- ln ∣ x - 2 ∣ + ln ∣ x - 3 ∣) + x + C

Solution steps

\int \frac{x ^{2} - 5 x + 9}{x ^{2} - 5 x + 6} d x

\frac{x ^{2} - 5 x + 9}{x ^{2} - 5 x + 6} = \frac{3}{x ^{2} - 5 x + 6} + 1

= \int \frac{3}{x ^{2} - 5 x + 6} + 1 d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{3}{x ^{2} - 5 x + 6} d x + \int 1 d x

\int \frac{3}{x ^{2} - 5 x + 6} d x = 3 (- ln ∣ x - 2 ∣ + ln ∣ x - 3 ∣)

\int 1 d x = x

= 3 (- ln ∣ x - 2 ∣ + ln ∣ x - 3 ∣) + x

Add a constant to the solution

= 3 (- ln ∣ x - 2 ∣ + ln ∣ x - 3 ∣) + x + C

\frac{\partial}{\partial x} (x, y, z)

x^{3}, 0, 3

f (x) = \frac{2 ln ( x )}{x}, at x = e

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

\int e^{- 2 x} \cdot x d x
