integral of (4x^3+5x)/(2x)

\int \frac{4 x ^{3} + 5 x}{2 x} d x

\frac{1}{2} (\frac{4 x ^{3}}{3} + 5 x) + C

Solution steps

\int \frac{4 x ^{3} + 5 x}{2 x} d x

Take the constant out:

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

= \frac{1}{2} \cdot \int \frac{4 x ^{3} + 5 x}{x} d x

Expand

\frac{4 x ^{3} + 5 x}{x} : \frac{4 x ^{3}}{x} + \frac{5 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}{2} (\int \frac{4 x ^{3}}{x} d x + \int \frac{5 x}{x} d x)

\int \frac{4 x ^{3}}{x} d x = \frac{4 x ^{3}}{3}

\int \frac{5 x}{x} d x = 5 x

= \frac{1}{2} (\frac{4 x ^{3}}{3} + 5 x)

Add a constant to the solution

= \frac{1}{2} (\frac{4 x ^{3}}{3} + 5 x) + C

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

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

\int - x cos (2 x + 3) d x

\int \frac{1}{cos ^{2} ( v )} d v

\int 3 x^{2} + 5 x + 7 d x
