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 choice from the following choices:  A) - 12  B) - 6  C) 12  D) 6  E) 24

Rationale: explanation : the sum of the roots of the quadratic equation ax 2 + bx + c = 0 are ( - b / a ) and the product of the roots are ( c / a ) . thus , in the equation ax 2 - 11 x + 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 answer : a
Answer: A
