Is the sum of the roots of the equation, x^2 + bx + c = 0, positive?

(1) b < 0

(2) c < 0

For any quadratic equation ax^2 + bx + c = 0

the sum of the roots = -b/aHere, comparing x^2 + bx + c = 0 with ax^2 + bx + c = 0

we find, a = 1, b = b and c = c

now Sum of the roots = -b/1 = -b

For sum of the roots to be positive, b must be NegativeStatement 1: b < 0SUFFICIENT

Statement 2: c < 0No information about b hence

NOT SUFFICIENT

Answer: option A
