Evaluate `int_-1^ 2|x^3-x|dx`

Explanation

To evaluate the integral \( \int_{-1}^{2} |x^3 - x| \, dx \), we will first analyze the function inside the absolute value to determine where it is positive and where it is negative.

### Step 1: Find the points where \( x^3 - x = 0 \)

To find the critical points, we set the expression inside the absolute value to zero:

\[
x^3 - x = 0
