I tried working out a solution to satisfy this equation and I got that this has no solution, however: $$1^2 + 2^2 + 2^2 = 3^2$$ so it does have a solution. I started off with the equation: $$a^2 + b^2 + c^2 = d^2$$ Therefore $a^2 + b^2 = d^2 - c^2$ and therefore: $$(a + b)^2 - 2ab = (d + c)...
@fonfox and George: I will just point out that there already is a tag name (square-numbers). I am not sure whether it was necessary to create a new tag, but maybe (perfect-squares) and (square-numbers) could be synonyms. See also here. — Martin Sleziak 10 secs ago
In fact, when I look at the synonyms for square-numbers, there already is a suggestion for this synonym.
