You have to solve equation I and II ,Give answer
1)If X>Y
2)If X<Y
3)If X≥ Y
4)If X≤ Y
5)If X=Y or cannot be established
- I. X2 – 5X – 84 = 0
II. Y2 – 9Y – 52 = 0
Answer
5)If X=Y or cannot be established
Explanation :
(X – 12)(X+7) = 0
X = 12, -7
(Y -13)(Y+4) = 0
Y = -4,13
13,12,-4,-7
- I. 4X2 + 17X + 15 = 0
II. 12Y2 + 19Y + 5 = 0
Answer
4)If X≤ Y
Explanation :
(X+3)(4X+5) = 0
X = -3, -5/4
(4X+5)(3X+1) = 0
X = -1/3,-5/4
-0.33,5/4,-5/4,-1/3
- I. X2 – 35X + 306 = 0
II. Y2 – 14Y – 51 = 0
Answer
3)If X≥ Y
Explanation :
(X – 17)(X-18) = 0
X = 17,18
(Y-17)(Y+3)= 0
Y = 17,-3
18,17,17,-3
- I. 2X2 – 9X + 9 = 0
II. Y2 – 11Y + 24 = 0
Answer
4)If X≤ Y
Explanation :
(2X-3)(X-3) = 0
X= 3,3/2
(Y-8)(Y-3) = 0
Y = 8,3
8,3,3,3/2
- I. X2 – 7X + 12 = 0
II. Y2 – 8Y+16 = 0
Answer
4)If X≤ Y
Explanation :
(X-3)(X-4) = 0
X = 3,4
(Y-4)(Y-4) =0
Y = 4,4
4,4,4,3
- I. 6X2 – 7X + 2 = 0
II. 12Y2 – 7Y+1 = 0
Answer
1)If X>Y
Explanation :
(2X-1)(3Y-2) = 0
X = ½,2/3
(4Y-1)(3Y-1) = 0
Y = ¼,1/3
0.6,0.5,0.3,0.2
- I. X2 = 4
II. Y2 + 4Y+4 = 0
Answer
3)If X≥ Y
Explanation :
X= +2, -2
(Y+2)(Y+2) = 0
Y = -2,-2
2,-2,-2,-2
- I. 3X2 +17X + 10=0
II. 10Y2 + 9Y+2 = 0
Answer
2)If X<Y
Explanation :
(3X+2)(X+5) = 0
X = -2/3, -5
(2Y+1)(5Y+2) = 0
Y = -1/2,-2/5
-0.4,-0.5,-0.6,-5
- I. X2 +X – 56 = 0
II.Y2 – 17Y+72 = 0
Answer
2)If X<Y
Explanation :
(X+8)(X-7) = 0
X=7,-8
(Y-9)(Y-8) = 0
Y=9,8
9,8,7,-8
- I. X2 -3X – 4 = 0
II. 3Y2 – 10Y+8 = 0
Answer
5)If X=Y or cannot be established
Explanation :
(X+1)(X-4) = 0
X = 4,-1
(3Y-4)(Y-2) = 0
Y = 2,4/3
4,2,1.3,-1
