Answer:

(x ^ 2 + 1 / (x ^ 2)) = 18

To find,

The value of (x - 1 / x)

Solution,

The value of (x - 1 / x) will be 4.

We can easily solve this problem by following the given steps.

According to the question,

We have the following expression:

(x ^ 2 + 1 / (x ^ 2)) = 18

Now to find the value of (x - 1 / x) , we will whole square this expression.

(x - 1 / x) ^ 2

Now, using the identity: (a - b) ^ 2 = a ^ 2 + b ^ 2 - 2ab to expand this expression

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

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

Now, putting the values of (x ^ 2 + 1 / (x ^ 2)) to be 18:

(x - 1 / x) ^ 2 = (18 - 2)

(x - 1 / x) ^ 2 underline =16

Removing the square from the left-hand side,

(x - 1 / x) = sqrt(16)

(x - 1 / x) = 4

Hence, the value of (x - 1 / x) is 4.
