    II. 5y2-22y+21=0

  • If x < y
  • If x > y
  • If x ≥ y
  • If x ≥ y
  • If relationship between x and y cannot be established
  • Explanation:

    I. 2x2-13x+21=0

    2x2-7x-6x+21=0

    x(2x-7)-3(2x-7)=0

    (2x-7)(x-3)=0

    x=7/2 or 3

    II. 5y2-22y+21=0

    5y2-15y-7y+21=

    5y(y-3)-7(y-3)=0
