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

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

\frac{1}{4} (\frac{2 x ^{3}}{3} - 3 x) + C

Solution steps

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

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{4} \cdot \int \frac{2 x ^{3} - 3 x}{x} d x

Expand

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

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \frac{1}{4} (\int \frac{2 x ^{3}}{x} d x - \int \frac{3 x}{x} d x)

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

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

= \frac{1}{4} (\frac{2 x ^{3}}{3} - 3 x)

Add a constant to the solution

= \frac{1}{4} (\frac{2 x ^{3}}{3} - 3 x) + C

\int - 6 x^{3} e^{x^{4}} d x

\int x 3 x^{2} + 7 d x

\int - 1 x^{4} e^{x^{5}} d x

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

\int \frac{1}{( cos ( x ) ) ^{4}} d x
