Otherwise, we will miss some important concepts. If it is not there please say so. So that we can consult books to know about the missing concepts, taught in the GEOMETRY - 15 video.

    Sir why cant we use AM>=GM in this as condition for it is min. Value and real non negative. I am 72 by applying this concept. Correct me if I am wrong.
    Edited part:-
    Ok I understood we cannot take a+b+c+d we will only take c+d as a,b values are already known so take can't be min or max as it is a constant number. We can use AM>=GM but only on c+d.
