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:
    
    $\int \left(- 5 x\right)\, dx = - 5 \int x\, dx$
    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: $- \frac{5 x^{2}}{2}$
  The result is: $\frac{2 x^{3}}{3} - \frac{5 x^{2}}{2}$
1. The integral of a constant is the constant times the variable of integration:
  
  $\int \left(-7\right)\, dx = - 7 x$
The result is: $\frac{2 x^{3}}{3} - \frac{5 x^{2}}{2} - 7 x$
Now simplify:

$\frac{x \left(4 x^{2} - 15 x - 42\right)}{6}$
Add the constant of integration:

$\frac{x \left(4 x^{2} - 15 x - 42\right)}{6}+ \mathrm{constant}$

The answer is:

$\frac{x \left(4 x^{2} - 15 x - 42\right)}{6}+ \mathrm{constant}$

$$\int \left(\left(2 x^{2} - 5 x\right) - 7\right)\, dx = C + \frac{2 x^{3}}{3} - \frac{5 x^{2}}{2} - 7 x$$
