because (x+1/x)/2 = M
so (x+1/x)=2M

and we have (x^2+1/x^2) = (x+1/x)^2 - 2

we get 4M^2-2 which is equal to (x^2+1/x^2)
now take average divide it by 2. so u ll get 2M^2-1
dats it. correct me if i m wrong


Yeah right....:):)

2m^2 - 1
Question arises why not 4 (2m^2-1)

x + 1/x = 2M
(x + 1/x) = 4M^2
x^2 + 1/x^2 = 4M^2 - 2
therefore avg of x^2 and 1/x^2 = (4M^2 - 2)/2
= 2M^2 - 1
