Question 735490
 I have an algebra project and one of the questions says " The difference between two perfect squares is 133.What is the smallest possible sum of the two perfect squares? " I found out that the answer is 205, but I don't understand why that is the answer.
------
Equation:
x^2 - y^2 = 133
(x-y)(x+y) = 133
-------
133 = 7*19 = (13-6)(13+6)
--------
Ans: 13^2+6^2 = 169 + 36 = 205
