Question

x-1/x =8 find the value of x+1/x​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

68

Step-by-step explanation:

(x - 1/x ) = 8

(x - 1/x)^2 = 8^2

(x - 1/x)^2 = 64

x^2 - 2 * x * 1/x + 1/x^2 = 64

x^2 - 2 + 1/x^2 = 64

x^2 + 1/x^2 = 64 + 2

x^2 + 1/x^2 = 66

x^2 + 1/x^2 + 2 = 66 + 2                        [add 2 on both sides for 2ab]

(x + 1/x)^2 = 68.

x + 1/x =  √68.
