Find the integral `intx^2(1-1/(x^2))dx`

Explanation

To solve the integral \( \int x^2 \left(1 - \frac{1}{x^2}\right) dx \), we can follow these steps:

### Step 1: Simplify the integrand
We start with the integral:
\[ \int x^2 \left(1 - \frac{1}{x^2}\right) dx \]
Distributing \( x^2 \) inside the parentheses gives us:
