If x + 1/x = 9 and x2 + 1/x2 = 53 , find the value of x - 1/x. Show steps.

Given : x + 1x = 9               ................1
x2 + 1x2= 53           .................2 
Sqauring the first equation we get ,  

(x + 1x)2 = 9 
x2+ 1x2+2.x.1x  = 81
 x2+ 1x2+ 2  = 81 
x2+1x2= 79
Which is contradicting the second equation . Hence the data provided by you is wrong .  Please recheck your query and post again .
