What is the integral of (2x^3-3)/x ?

The integral of (2x^3-3)/x is (2x^3)/3-3ln|x|+C

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

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

\frac{2 x ^{3}}{3} - 3 ln ∣ x ∣ + C

Solution steps

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

Expand

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

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

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

\int \frac{3}{x} d x = 3 ln ∣ x ∣

= \frac{2 x ^{3}}{3} - 3 ln ∣ x ∣

Add a constant to the solution

= \frac{2 x ^{3}}{3} - 3 ln ∣ x ∣ + C

\int (2 csc^{2} (x) - 3 sec^{2} (x)) d x

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

\int \frac{x ^{2} + 4 x - 5}{x + 2} d x

\int \frac{x ^{4}}{( x - 1 ) ^{2} ( x + 2 )} d x

\int cos^{6} (\frac{5 x}{2}) d x
