Hello, I am having trouble differentiating this problem, it looks like the quotient rule is being used within the product rule, but I don't know how to combine the two of them.

f(x)= ln(x+1/x-1) I started using the product rule but then I got lost when I had to differentiate the second term, because this would be a quotient rule in this term. If someone could illustrate how to differentiate this, Thanks...
