$$\int\limits_{0}^{1} \left(\left(x^{3} - x\right) + 2\right)\, dx$$

Integral(x^3 - x + 2, (x, 0, 1))

Detail solution

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

$\frac{x \left(x^{3} - 2 x + 8\right)}{4}$
Add the constant of integration:

$\frac{x \left(x^{3} - 2 x + 8\right)}{4}+ \mathrm{constant}$

The answer is:

$\frac{x \left(x^{3} - 2 x + 8\right)}{4}+ \mathrm{constant}$
