Answer 1

HERE IS YOUR ANSWER

IF IT IS CORRECT THEN WELL AND GOOD

IF IT IS WRONG THEN SORRY

Answer 2

Answer:

8

Step-by-step explanation:

Given: x^2+ 1/x^2 = 66

x -1/x = ?

(x -1/x)^2 = x^2 + 1/x^2 - 2(x.1/x)

(x - 1/x) ^2 = 66 -2

(x - 1/x) ^2 = 64

square rooting both sides, we get

x - 1/x = √64

(x - 1/x) = 8
