Integral(2*x^3 + 4*x^2 - 6*x - 1*8, (x, 0, 6))

Detail solution

Integrate term-by-term:
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int 2 x^{3}\, dx = 2 \int x^{3}\, dx$
  1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
    
    $\int x^{3}\, dx = \frac{x^{4}}{4}$
  So, the result is: $\frac{x^{4}}{2}$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int 4 x^{2}\, dx = 4 \int x^{2}\, dx$
  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: $\frac{4 x^{3}}{3}$
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int \left(- 6 x\right)\, dx = - \int 6 x\, dx$
  1. The integral of a constant times a function is the constant times the integral of the function:
    
    $\int 6 x\, dx = 6 \int x\, dx$
    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: $3 x^{2}$
  So, the result is: $- 3 x^{2}$
1. The integral of a constant is the constant times the variable of integration:
  
  $\int \left(\left(-1\right) 8\right)\, dx = - 8 x$
The result is: $\frac{x^{4}}{2} + \frac{4 x^{3}}{3} - 3 x^{2} - 8 x$
Now simplify:

$\frac{x \left(3 x^{3} + 8 x^{2} - 18 x - 48\right)}{6}$
Add the constant of integration:

$\frac{x \left(3 x^{3} + 8 x^{2} - 18 x - 48\right)}{6}+ \mathrm{constant}$

The answer is:

$\frac{x \left(3 x^{3} + 8 x^{2} - 18 x - 48\right)}{6}+ \mathrm{constant}$
