Direction (Q. 6-10): In the following questions, there are two equations (I) and (II) solve the equations and answer according to following codes:
1) if x < y              2) if x > y              3) if x = y              4) if x >= y              5) if x <= y

Q6.  I. 2x^2 – 13x + 21 = 0              II. 2y^2 – 7y + 3 = 0

Q7. I. x^2 – 12x + 35 = 0             II. 6y^2 + 11y +3 = 0

Q8. I. 2x^2 – 17 x +21 = 0             II. y^2 – 15y + 56 = 0

Q9. I. x^2 + 2x – 8 = 0              II. 2y^2 – 15y + 28 = 0

Q10. I. x = √(1/9)              II. 9y^2 – 6y + 1 = 0
