$$\int\limits_{0}^{3} \left(x^{2} - 15\right)\, dx$$

Integral(x^2 - 15, (x, 0, 3))

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 a constant is the constant times the variable of integration:
  
  $\int \left(-15\right)\, dx = - 15 x$
The result is: $\frac{x^{3}}{3} - 15 x$
Now simplify:

$\frac{x \left(x^{2} - 45\right)}{3}$
Add the constant of integration:

$\frac{x \left(x^{2} - 45\right)}{3}+ \mathrm{constant}$

The answer is:

$\frac{x \left(x^{2} - 45\right)}{3}+ \mathrm{constant}$
