I. 2x² + 17x + 35 = 0

II. 3y² + 17y + 24 = 0

x>y

x>=y

No Relation

y>x

Explanation:

I. 2x² + 17x + 35 = 0
2x² + 10x+ 7x + 35 = 0
2x (x+ 5) +7 (x+ 5) = 0
(2x+ 7) (x+ 5) =0
x = (-7)/2, -5
II. 3y² + 17y + 24 = 0
3y² + 9y + 8y + 24 = 0
3y (y + 3) + 8 (y+ 3) = 0
(y+ 3) (3y + 8) = 0
y= -3, -8/3
y > x
