Answer 2

Answer:

The value of (x- 1/x) = 7 or -7

Step-by-step explanation:

This question is based on the formula = (a -1/a)² = a²+1/a² -2

x²+ 1/x² = 51

subtract 2 in the both side of the equation

x²+ 1/x² -2 = 51-2

x²+ 1/x² -2 = 49

(x- 1/x)² = 49

(x- 1/x) = 7 or -7

The value of (x- 1/x) = 7 or -7
