In the quadratic equation ax2 - x - 12 = 0, if the sum of two roots is 1, what is the product of the two roots? Choose the correct answer
A) -12
B) -6
C) 12
D) 6
E) 24
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 - 11x + 40 = 0, where a = a, b = - 1 and c = -12.   we get, sum of the roots = 1 / a = 1   a = 1   Product of the roots = -12 / 1 =-12   -12NSWER: -12
