( x+ 1/x ) ^2 = x^2 +1/x^2 +2
( x- 1/x ) ^2= (x + 1/x) ^2 - 4
x-1/x = root {( 144 ) - 4}
x - 1/x = root 140 = 2 root 35
( x- 1/x ) ^2= (x + 1/x) ^2 - 4
x-1/x = root {( 144 ) - 4}
x - 1/x = root 140 = 2 root 35

I am not able to understand how to have done the question
( x+ 1/x )^2 = ( x -1/x) ^2 + 4
put on this eq.
