In the following question, two equations numbered 1 and 2 are given. You have to solve both the equations and determine the relation between a and b. 1. 5a2-18a+9=0 2. 3b2+5b-2=0

Correct Answer: a > b

Explanation:

From solving 1 and 2 we get,


 


1.


5a(a-3)-3(a-3) = 0


 


(5a-3)(a-3) = 0


 


a = 3 or 3/5


 


2. 


 


3b(b+2)-1(b+2) = 0


 


b = -2 or b = 1/3


 


Here when a = 3, a > b for b = -2 and b = 1/3


 


when a = 3/5. a > b for b = -2 and b = 1/3.


 


Hence, it is clear that a > b.
