How do you differentiate f(x)=ln(x^2-x)f(x)=ln(x2x) using the chain rule.?

f'(x)=(2x-1)/(x^2-x)

Explanation:

The chain rule for the specific case of a natural logarithm function can be derived as follows:

d/dxln(x)=1/x" "=>" "d/dxln(g(x))=1/(g(x))*g'(x)

So, for f(x)=ln(x^2-x), we see that

f'(x)=1/(x^2-x)(d/dx(x^2-x))

f'(x)=1/(x^2-x)(2x-1)

f'(x)=(2x-1)/(x^2-x)
