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

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

x^{3} + \frac{x ^{2}}{4} + C

Solution steps

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

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

\int \frac{x}{2} d x = \frac{x ^{2}}{4}

= x^{3} + \frac{x ^{2}}{4}

Add a constant to the solution

= x^{3} + \frac{x ^{2}}{4} + C
