  1. If (x+2) is the HCF of x2 + ax + b and x2 + cx + d , then which one of the following is correct ?
    1. a + c = b + d
    2. 2a + b = 2c + d
    3. b + 2c = 2a + d
    4. b - 2c = 2a - d
  1. Correct Option: C

    If (x+2) is the HCF of x2 + ax + b and x2 + cx + d.
    Then, (-2)2 -2a +b = (-2)2 -2c + d
    b + 2c = 2a + d
