Simplify: `(x+2/x)^3+\ (x-2/x)^3`

Explanation

To simplify the expression \((x + \frac{2}{x})^3 + (x - \frac{2}{x})^3\), we can use the formula for the sum of cubes and the properties of algebraic identities.

### Step-by-Step Solution:

1. **Identify \(a\) and \(b\)**:
Let \(a = x\) and \(b = \frac{2}{x}\). Then, we can rewrite the expression as:
\[
(a + b)^3 + (a - b)^3
