integral of (3x^3-6x^2+2)/x

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

x^{3} - 3 x^{2} + 2 ln ∣ x ∣ + C

Solution steps

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

Expand

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

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

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

\int 6 x d x = 3 x^{2}

\int \frac{2}{x} d x = 2 ln ∣ x ∣

= x^{3} - 3 x^{2} + 2 ln ∣ x ∣

Add a constant to the solution

= x^{3} - 3 x^{2} + 2 ln ∣ x ∣ + C

\int (x^{7} + 5) d x

\int 4 sec^{2} (4 x) tan (4 x) d x

\int \frac{e ^{x}}{e ^{2 x} - 6 e ^{x} + 13} d x

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

\int (3 x + a) sin (x) d x
