  • Question
  • In each of these questions, two equations (I) and (II) are given. I. 2x2+19x+42 = 0II. 4y2+43y+30 = 0


  • Options
  • A. x > y
  • B. x < y
  • C. x ? y
  • D. x ? y

  • Correct Answer
  •  

    Explanation

    I. 2x2 + 19x + 42 = 0

    2x2 + 12x + 7x + 42 = 0

    2x (x+6) + 7(x +6) = 0

    (2x+7) (x+6) = 0 x = -7/2, -6 I

    I. 4y2 + 43y + 30 = 0

    4y2 +40y + 3y + 30 = 0

    4y(y + 10) + 3(y + 10) (4y + 3)(y + 10) = 0

    y = -3/4, -10

    So answer is no relation.
