This is how I would do it..Lesson learnt..Whenever you see a fraction with a constant as it's numerator,reciprocate it back..From there onwards,you can simply apply your usual (level 1) differential skills that you have learnt..So,the constant term is the hint..Hope it helps.. :)

If it is not a constant term(any whole number/integer),let's say a function,you need to use the quotient rule.The numerator makes a difference to whether using the usual differentiation or quotient rule should be deemed as necessary..
