In the quadratic equation ax2 + 8x + 16 = 0, if the sum of two roots is -8, what is the product of the two roots?
Choose the correct option.
A) 16 B) 14 C) 20 D) 15 E) 13
Explanation:   The sum of the roots of the quadratic equation ax2 + bx + c = 0 are (-b/a) and the product of the roots are (c/a).   Thus, in the equation ax2 +8 x + 40 = 0, where a = a, b = 8 and c = 16.   we get, sum of the roots = -8 / a= -8   a= 1   Product of the roots = 16 / 1=
