\int\limits_{x}^{2} \left(y^{2} + y\right)\, dy

Integral(y + y^2, (y, x, 2))

Detail solution

Integrate term-by-term:
1. The integral of $y^{n}$ is $\frac{y^{n + 1}}{n + 1}$ when $n \neq -1$ :
  
  $\int y^{2}\, dy = \frac{y^{3}}{3}$
1. The integral of $y^{n}$ is $\frac{y^{n + 1}}{n + 1}$ when $n \neq -1$ :
  
  $\int y\, dy = \frac{y^{2}}{2}$
The result is: $\frac{y^{3}}{3} + \frac{y^{2}}{2}$
Now simplify:

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

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

The answer is:

\frac{y^{2} \left(2 y + 3\right)}{6}+ \mathrm{constant}
