AI explanation

The sum of the zeros of the quadratic polynomial ax^2 + bx + c is given by the formula -b/a. Rewriting the given polynomial in standard form yields -x^2 - 3x + 2, where a = -1 and b = -3. Applying the formula, the sum alpha + beta equals -(-3) / (-1), which is -3. Since -3 is not listed among the provided numerical options, the correct choice is none of these.
