$$\int\limits_{e}^{\infty} \frac{x \log{\left(x \right)}^{2}}{1}\, dx$$

Integral((x*log(x)^2)/1, (x, E, oo))

Detail solution

The integral of a constant times a function is the constant times the integral of the function:

$\int \frac{x \log{\left(x \right)}^{2}}{1}\, dx = \int x \log{\left(x \right)}^{2}\, dx$
1. Don't know the steps in finding this integral.
  
  But the integral is
  
  $\frac{x^{2} \log{\left(x \right)}^{2}}{2} - \frac{x^{2} \log{\left(x \right)}}{2} + \frac{x^{2}}{4}$
So, the result is: $\frac{x^{2} \log{\left(x \right)}^{2}}{2} - \frac{x^{2} \log{\left(x \right)}}{2} + \frac{x^{2}}{4}$
Now simplify:

$\frac{x^{2} \left(2 \log{\left(x \right)}^{2} - 2 \log{\left(x \right)} + 1\right)}{4}$
Add the constant of integration:

$\frac{x^{2} \left(2 \log{\left(x \right)}^{2} - 2 \log{\left(x \right)} + 1\right)}{4}+ \mathrm{constant}$

The answer is:

$\frac{x^{2} \left(2 \log{\left(x \right)}^{2} - 2 \log{\left(x \right)} + 1\right)}{4}+ \mathrm{constant}$

$$\int \frac{x \log{\left(x \right)}^{2}}{1}\, dx = C + \frac{x^{2} \log{\left(x \right)}^{2}}{2} - \frac{x^{2} \log{\left(x \right)}}{2} + \frac{x^{2}}{4}$$
