Find the derivative of the function below in two ways.
F(x) = (x  7 x sqrt(x)) / sqrt(x)
(a) By using the Quotient Rule.
(b) By simplifying first.

drwls,
Can't you do either of these? Do you know the quotient rule?
If you simplify first, you get
F(x) = sqrt x  7x
Try differentiating that term by term. There are only two terms.
Someone will gladly critique your work.
