$$\int\limits_{-4}^{1} \left(x^{2} + \left(4 - 3 x\right)\right)\, dx$$

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

Detail solution

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

$\frac{x \left(2 x^{2} - 9 x + 24\right)}{6}$
Add the constant of integration:

$\frac{x \left(2 x^{2} - 9 x + 24\right)}{6}+ \mathrm{constant}$

The answer is:

$\frac{x \left(2 x^{2} - 9 x + 24\right)}{6}+ \mathrm{constant}$
