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

Integral(x^3 + 3*x^2, (x, -3, 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:
  
  $\int 3 x^{2}\, dx = 3 \int x^{2}\, dx$
  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: $x^{3}$
The result is: $\frac{x^{4}}{4} + x^{3}$
Now simplify:

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

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

The answer is:

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