C3 DIFFERENTIATION help pls

image.jpgI used the product rule but the mark scheme has an answer with the v^2 part on the bottom of the fraction like in the quotient rule and I thought you'd just use the product rule since you can just take the denominator to the top with a negative power??

Might as well just use the quotient rule where possible, seems easier imo.
