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

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

\frac{x ^{3}}{3} + 5 ln ∣ x - 3 ∣ + C

Solution steps

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

Long division

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

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

\int x^{2} d x = \frac{x ^{3}}{3}

\int \frac{5}{x - 3} d x = 5 ln ∣ x - 3 ∣

= \frac{x ^{3}}{3} + 5 ln ∣ x - 3 ∣

Add a constant to the solution

= \frac{x ^{3}}{3} + 5 ln ∣ x - 3 ∣ + C

\int \frac{5}{x ^{2} + 16} d x

\int \frac{1}{2} x - 1 d x

\int 2 (2 x + 1)^{3} d x

\int \frac{4 + 12 x}{1 + 2 x + 3 x ^{2}} d x

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