Sum and product of roots of x² + 7x + 12 = 0:
ASum = -7, Product = 12 (Vieta's: -b/a, c/a)
BSum = -7, Product = 12
CSum = 7, Product = -12
DSum = 7
Answer & Solution
Correct answer: A. Sum = -7, Product = 12 (Vieta's: -b/a, c/a)
For ax² + bx + c = 0: sum of roots = -b/a, product = c/a. Here a=1, b=7, c=12. Sum = -7, Product = 12. Roots are -3, -4 (verify: -7 sum, 12 product ✓).
