gollark: Assume there are integers x, y satisfying x²-y²=2(x-y)(x+y)=2x-y, x+y are both integers because they are a sum/difference of integersx, y >= 0 because (-x)²=x² so just ignore negative solutions since they only exist if a positive one does2 has the factors 2,1 so x-y, x+y must be 1, 2 in some orderx-y, x+y differ by 2yx-y, x+y differ by 12y=1y=½But y is an integer
gollark: We are having such advanced intellectual conversations.
