  • Question
  • In the given questions, two equations numbered I and II are given. Solve both the equation and mark the appropriate answer. I. x2?5x ?24 = 0II. 2y2+ 19y + 35 = 0


  • Options
  • A. x > y
  • B. x>y
  • C. x < y
  • D. x
  • Correct Answer
  •  

    Explanation

    x^2?5x ?24 = 0

    (x-8) (x+3)

    x = 8, -3

    II. 2y^2+ 19y + 35 = 0

    (2y+7) (y+7)y= -7, -5/2

    So can?t be determined
