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

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

Detail solution

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:
  
  $\int 2 x^{2}\, dx = 2 \int x^{2}\, dx$
  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 $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
  
  $\int x\, dx = \frac{x^{2}}{2}$
The result is: $\frac{x^{4}}{4} + \frac{2 x^{3}}{3} + \frac{x^{2}}{2}$
Now simplify:

$\frac{x^{2} \cdot \left(3 x^{2} + 8 x + 6\right)}{12}$
Add the constant of integration:

$\frac{x^{2} \cdot \left(3 x^{2} + 8 x + 6\right)}{12}+ \mathrm{constant}$

The answer is:

$\frac{x^{2} \cdot \left(3 x^{2} + 8 x + 6\right)}{12}+ \mathrm{constant}$
