Okay, I just thought you might want to see something else.
I think #2 was better
that makes a square. So start with
You have 2 equations which say what b must be added to b + 56 and b + 200 that give you two squares. Well the next square after 56 is 64 so b = 8 is a possibility but 200 + 8 is not a square.
Then next square is 81 which means in b + 56 = 81 b would be 25. Plugging in b into the second equation 25 + 200 = 225 which is a square too. You are done, b = 25.
Please expain why you get
Comparing coefficients gives .
Hence you must add :
What must be added to the following expression to make it a perfect square?
