Find the solutions of the rational polynomial equation `(x^2-4)/(x^3-x^2-6x)=0`.

Explanation

To solve the rational polynomial equation \((x^2 - 4)/(x^3 - x^2 - 6x) = 0\), we will follow these steps:

### Step 1: Set the numerator equal to zero
The rational polynomial is equal to zero when its numerator is equal to zero (as long as the denominator is not zero). Therefore, we set the numerator \(x^2 - 4\) equal to zero:
\[ x^2 - 4 = 0 \]
