I. 5x2+8x+3=0

    II. 3y2+7y+4=0

  • x ≤ y
  • x ≥ y
  • Relationship between x and y cannot be established
  • x < y
  • x > y
  • Explanation:

    I. 5x2+8x+3=0

    ⇒ 5x2+5x+3x+3=0

    ⇒ 5x(x+1)+3(x+1)=0

    ⇒ (x+1)(5x+3)=0

    ⇒               x=-1,-3/5

    II. 3y2+7y+4=0

    ⇒ 3y2+4y+3y+4=0

    ⇒ y(3y+4)+1(3y+4)=0

    ⇒ (3y+4)(y+1)=0

    ⇒                y=4/3,-1

    ∴              x ≥ y
