Detail solution

Integrate term-by-term:
1. Integrate term-by-term:
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int 2 x^{2}\, dx = 2 \int x^{2}\, dx$
    1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
      
      $\int x^{2}\, dx = \frac{x^{3}}{3}$
    So, the result is: $\frac{2 x^{3}}{3}$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int 3 x\, dx = 3 \int x\, dx$
    1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
      
      $\int x\, dx = \frac{x^{2}}{2}$
    So, the result is: $\frac{3 x^{2}}{2}$
  The result is: $\frac{2 x^{3}}{3} + \frac{3 x^{2}}{2}$
1. The integral of a constant is the constant times the variable of integration:
  
  $\int \left(-1\right)\, dx = - x$
The result is: $\frac{2 x^{3}}{3} + \frac{3 x^{2}}{2} - x$
Now simplify:

$\frac{x \left(4 x^{2} + 9 x - 6\right)}{6}$
Add the constant of integration:

$\frac{x \left(4 x^{2} + 9 x - 6\right)}{6}+ \mathrm{constant}$

The answer is:

$\frac{x \left(4 x^{2} + 9 x - 6\right)}{6}+ \mathrm{constant}$
