Problem Num : 3 Type: Modification Topic:Polynomials  Theme:None Adjustment# : 3 Difficulty: 500 level
Category	Factoring and Expanding
Analysis	(x-1)(y-1)=xy-(x+y)+1
Solution/Hint	(1) xy=x+y then, (x-1)(y-1)=xy-(x+y)+1=1 (2)if x=y, then (x-1)(y-1)=(x-1)^2. Therefore, we don't know if it is same as 1 or not.
