Good day day to you busy bee. Let's hope I'm a good teacher.

So you understand the process by which was obtained from

Explanation:

For any given inequality 0 or , we can determine which is greater than which, in the former , in the latter

In the case where , this means that this expression is negative. By observing the expression . the only way for it to be negative is if ,(not true due to question constraints) or if .

For , the expression is positive, hence

By letting each of q and p be equal to , we establish an expression which is greater than/lesser than .

boils down to ,so now we can determine whether or .

Don't hesitate to ask for further clarification if necessary.
