1

The integral of the natural logarithm is given by the following formula, $\displaystyle\int\ln(x)dx=x\ln(x)-x$

$x\ln\left|x\right|-x$
2

As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration $C$

$x\ln\left|x\right|-x+C_0$

##  Final answer to the problem

$x\ln\left|x\right|-x+C_0$
