This is not the case.How then can 2nm = 15??
Moreover,

Can 6 be expressed as the difference between 2 squares? The only Integers that six can be divided by to give another integer are:
1, 2, 3 and 6,

Hence : (x + y) = 3 or 6
(x - y) = 2 or 1
What are the solutions to x and y here??
Thank you; Ravin

In the article you refer to a = n² - m², b = 2nm. Thus your triple should be written as

15, 8, 17

with no apparent contradiction.

x+y and x-y are of the same parity.
