I hope this would help you

The answer is +10 or -10.

Step-by-step explanation:

At first we have to find the value of (x-1/x)^2

The formula of (a-b)^2 is (a^2+b^2-2ab).

so the value of (x-1/x)^2 is x^2 + 1/x^2- 2(x)(1/x).

we have the value of x^2+1/x^2 as 102 and the value of 2(x)(1/x) is 2.

So answer of (x-1/x)^2 is 102-2 = 100

By square rooting, we get (x-1/x)= +10 or -10
