If the roots of the quadratic equation ax^2 + bx + c = 0 are 3 and 4, what is the relationship betwe

A. a = 7, b = -21, c = 12

B. a = 12, b = -21, c = 7

C. a = 1, b = -7, c = 12

D. a = 1, b = -12, c = 36

E. None of the above

Answer: C. a = 1, b = -7, c = 12

The sum of the roots (3 + 4) = -b/a and the product of the roots (3 * 4) = c/a, leading to the coefficients being a = 1, b = -7, c = 12.
