the value will be 1
(x-1/x)^2-2=x^+1/x^2
1 = x^2+1/x^2

karthikeya12345: no i cant understand explain be better
prem33: make square of x-1/x you will get x^2+1/x^2 -2 when you add 2
prem33: you will get x^2 + 1/x^2
prem33: (x-1/x)^2 +2 = x^2 +1/x^2
prem33: (root 3)^2 +2 =5
prem33: sorry i have made a silly mistake
