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

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

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

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

The answer is:

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