You have a choice here.
- Use the quotient rule
- First divide the x in the denominator into every term of the numerator, then find the derivative term by term using the power rule (my choice).
First you should rewrite √x as x1/2.
Using 2nd choice:
y = 2x-1-2x+x4-x-1/2
Then y' = -2x-2.... (you should be able to take it from there)
