integral of ((x-3)^3)/x

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

\frac{x ^{3}}{3} - \frac{9 x ^{2}}{2} + 27 x - 27 ln ∣ x ∣ + C

Solution steps

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

Long division

\frac{( x - 3 ) ^{3}}{x} : x^{2} - 9 x + 27 - \frac{27}{x}

= \int x^{2} - 9 x + 27 - \frac{27}{x} 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 9 x d x + \int 27 d x - \int \frac{27}{x} d x

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

\int 9 x d x = \frac{9 x ^{2}}{2}

\int 27 d x = 27 x

\int \frac{27}{x} d x = 27 ln ∣ x ∣

= \frac{x ^{3}}{3} - \frac{9 x ^{2}}{2} + 27 x - 27 ln ∣ x ∣

Add a constant to the solution

= \frac{x ^{3}}{3} - \frac{9 x ^{2}}{2} + 27 x - 27 ln ∣ x ∣ + C

\int \frac{9}{3 + 9 x} d x

\int \frac{1}{1 - 4 y} d y

(x + 1)^{3} (1 - x)

\frac{d}{d x} (5 e^{x} sin (x))
