updating previous question so easier to understand

im using chain rule to answer this question:

f(x) = -5 sqrt(x^2 - 4x + 1)
what is f'(x)?

tried to use calculator to get the answer to base my answer off of but this is a nonreal number. does this mean i will have to use imaginary numbers? please help
