thanks Reiny :))

OOPS I DIDN"T SEE IT THANKS

the whole thing confuses me honestly

(a-b)^2 confuses me

I'm pretty sure you can use the Pythagorean Triples Have you ever heard of a three four five triangle? sorry I don't think that was much help but rather a hint

A "Pythagorean Triple" is a set of positive integers, a, b and c that fits the rule: a2 + b2 = c2 Example: The smallest Pythagorean Triple is 3, 4 and 5. Let's check it: 32 + 42 = 52 Calculating this becomes: 9 + 16 = 25 And that is true

(3,4,5) (5,12,13) (7,24,25) (8,15,17) (9,40,41) (11,60,61) (12,35,37) (13,84,85) (15,112,113) (16,63,65) (17,144,145) (19,180,181) (20,21,29) (20,99,101) (21,220,221) (23,264,265) (24,143,145) (25,312,313) (27,364,365) (28,45,53) (28,195,197) (29,420,421)...
