D Correct answer
Explanation

For ax^2 + bx + c = 0, the product of the roots is c/a. Here, c/a = (-18)/(-2) = 9.

AI explanation

Treating the expression as the quadratic equation -2x^2 - 6x - 18 = 0 and using the formula for the product of roots which is c/a, we get -18/-2. Simplifying this fraction gives 9.
