Evaluate the definite integral of x^(-1)

I'm just starting calc II and I didn't manage to see a lot of examples, but from the basic information I have got so far I'm confused about this one:

and by evaluating it I get that I need to evaluate from -3 to -6 , how do I evaluate the ln|x| for negative numbers, or there is a trick I don't see...

thank you,

The key here is that the argument of the logarithm is , not just .
