Find the roots of the rational polynomial equation `(x^2-6x+8)/(x+2)=0`.

Explanation

To find the roots of the rational polynomial equation \((x^2 - 6x + 8)/(x + 2) = 0\), we can follow these steps:

### Step 1: Set the Numerator Equal to Zero
Since a fraction is equal to zero when its numerator is zero (and the denominator is not zero), we start by setting the numerator equal to zero:
\[ x^2 - 6x + 8 = 0 \]
