Question 320787: the sum of two numbers is 5 and their difference is 2.which of the following could be the difference of their squares
Answer by Alan3354(69443)   (Show Source):
You can put this solution on YOUR website! If the difference is 2, then they're either both odd, or both even.
2 odd numbers add to an even number.
2 even numbers add to an even number, too, so the sum cannot be 5 unless they're not integers.
----------------------
--> 1.5 & 3.5
You can calculate the difference of the squares.
