d) If X ≤ Y
e) If X = Y or cannot be established
26). I. 4X² – 19X + 12= 0
II. 3Y² + 8Y + 4 = 0

a)
b)
c)
d)
e)
(x-4)(4x-3) = 0
X=4,3/4
(y+2)(3y+2) = 0
y=-2, -2/3
Hence, x > y
27). I. X² = 729
II. Y – √324 = √81

a)
b)
c)
d)
e)
X= ±27
Y = 9+18 = 27
Hence, x ≤ y
28). I. X² + X – 56= 0
II. Y² – 17Y + 72 = 0

a)
b)
c)
d)
e)
(x+8)(x-7) = 0
X=7,-8
(y-8)(y-9) = 0
Y=8, 9
Therefore X < Y
29). I. 20X² – 17X + 3= 0
II. 20Y² – 9Y + 1 = 0

a)
b)
c)
d)
e)
(4x-1)(5x-3) = 0
X=1/4, 3/5
(4y-1)(5y-1) =0
Y = 1/4, 1/5
Therefore, X ≥ Y
30). I. 3X² – 10X + 8= 0
