integral of (x^3-4x-10)/(x^2-x-6)

\int \frac{x ^{3} - 4 x - 10}{x ^{2} - x - 6} d x

\frac{x ^{2}}{2} + x + 2 ln ∣ x + 2 ∣ + ln ∣ x - 3 ∣ + C

Solution steps

\int \frac{x ^{3} - 4 x - 10}{x ^{2} - x - 6} d x

Take the partial fraction of

\frac{x ^{3} - 4 x - 10}{x ^{2} - x - 6} : x + 1 + \frac{2}{x + 2} + \frac{1}{x - 3}

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

\int x d x = \frac{x ^{2}}{2}

\int 1 d x = x

\int \frac{2}{x + 2} d x = 2 ln ∣ x + 2 ∣

\int \frac{1}{x - 3} d x = ln ∣ x - 3 ∣

= \frac{x ^{2}}{2} + x + 2 ln ∣ x + 2 ∣ + ln ∣ x - 3 ∣

Add a constant to the solution

= \frac{x ^{2}}{2} + x + 2 ln ∣ x + 2 ∣ + ln ∣ x - 3 ∣ + C

\int \frac{3 - 2 x}{5 x ^{2} + 7} d x

\int_{- 1}^{3} (x^{3} - 2) d x

\int - 2 y^{2} d y

x \to 0 lim (\frac{x}{3})

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