$6x^{3}+2x^2+C_0$

## Step-by-step explanation

Problem to solve:

$\int\left(18x^2+4x\right)dx$
1

The integral of a sum of two or more functions is equal to the sum of their integrals

$\int18x^2dx+\int4xdx$
2

Take the constant out of the integral

$18\int x^2dx+\int4xdx$

$6x^{3}+2x^2+C_0$
$\int\left(18x^2+4x\right)dx$
