5)If X=Y or cannot be established
- I. 4X2 Â – 19X + 12= 0
II. 3Y2 + 8Y + 4 = 0Answer –1)If X>Y
Explanation :
(x-4)(4x-3) = 0
X=4,3/4
(y+2)(3y+2) = 0
y=-2, -2/3
4,3/4,-2/3,-2
Xxyy = x>y - I. X2 = 729
II. Y – √324 = √81Answer –4)If X≤ Y
Explanation :
X= ±27
Y = 9+18 = 27
x≤y - I. X2  + X – 56= 0
II. Y2 – 17Y + 72 = 0Answer –2)If X<Y
Explanation :
(x+8)(x-7) = 0
X=7,-8
(y-8)(y-9) = 0
Y=8, 9
9,8,7,-8
Yyxx = x<y - I. 20X2 Â – 17X + 3= 0
II. 20Y2 – 9Y + 1 = 0Answer –3)If X≥ Y
Explanation :
(4x-1)(5x-3) = 0
X=1/4, 3/5
(4y-1)(5y-1) =0
Y = 1/4, 1/5
3/5, ¼,1/4, 1/5
Xxyy => X≥ Y - I. 3X2  – 10X + 8= 0
II. Y2 +Â 3Y – 4 = 0Answer –1)If X>Y
Explanation :
(x-2)(3x-4) = 0
X=2, 4/3
(y-1)(y+4) = 0
Y = 1, -4
2,4/3,1,-4
Xxyy => x>y - I. X2 Â + 5X + 6= 0
II. Y2 + 3Y + 2 = 0Answer –4)If X≤ Y
Explanation :
(x+2)(x+3) = 0
X=-2,-3
(y+1)(y+2) = 0
Y=-1,-2
-1,-2,-2,-3
Yyxx => x≤y - I. 2X2  + 5X + 2= 0
II. 4Y2 – 1 = 0Answer –4)If X≤ Y
Explanation :
(2x+1)(x+2) = 0
X= – 1/2, -2
Y = ½, -1/2
½, -1/2, -1/2, -2
Yyxx => x≤y - I. X2  + 14X -72= 0
II. 3Y2 + 14Y + 15 = 0Answer – 5)If X=Y or cannot be established
Explanation :
(x-4)(x+18) = 0
X=4,-18
(y+3)(3y+5) = 0
Y= -3, -5/3
4,-5/3, -3, -18
xyyx - I. X2 Â + 8X + 15= 0

Explanation :
(x+5)(x+3) = 0
X=-5,-3
(y-4)(y+3) = 0
Y=4,-3
4,-3,-3,-5
Yyxx => x≤y - I. 4X2  – 13X – 12= 0
II. Y2 – 7Y – 60 = 0Answer – 5)If X=Y or cannot be established
Explanation :
(x-4)(4x+3) = 0
X=4, -3/4
