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

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

Detail solution

Integrate term-by-term:
1. The integral of a constant times a function is the constant times the integral of the function:
  
  $\int 3 x^{3}\, dx = 3 \int x^{3}\, dx$
  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: $\frac{3 x^{4}}{4}$
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: $\frac{3 x^{4}}{4} + \frac{3 x^{2}}{2}$
Now simplify:

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

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

The answer is:

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