What is the derivative with respect to x of . . . . xy'/y^2
I can get as far as derivative of xy' = y' + xy"
But I dont know what to do about the bit on the bottom . .
I'm guessing i need the quotient rule somehow . .

You have to use the quotient rule: The derivative of is equal to .
In your problem:
, as you correctly found (using the product rule).
