1. The sum of the roots of a quadratic equation ax^2 + bx + c = 0 is given by -b/a. In this case, a = 2 and b = -8, so the sum of the roots is (-(-8)/2) = 4.2. The product of the roots of a quadratic equation ax^2 + bx + c = 0 is given by c/a. In this case, a = 2 and c = 6, so the product of the roots is (6/2) = 3.
