We strive to simplify the expression first as far as possible, so as to facilitate simpler differentiation.
Whenever I write d/dx in the lines, it means that I have yet to differentiate the expression (or simply put, the expression is going to be differentiated); I am just transforming the expression into another form. The moment I no longer have the d/dx in the lines, it means that I have already differentiated the expression.
If you have not learnt it yet (probably in a few weeks time you would be doing so anyway, since you are already at this section of differentiation), another way to do this is to use the quotient rule in differentiation to solve this, though it takes a much longer time to achieve the answer.
