Jesus . <| sep |> This company has had 200 oil spills in the past several years . <| sep |> It ' s true if A and B are both integers . Every integer can be written in the form of 3 k , 3 k 1 or 3 k 2 . As division mod 3 yield 0 , 1 or 2 as the result . So that means the squares can be written as 3 k 2 33 k 2 which is of the form 3 k 3 k 12 9 k 2 6 k 1 33 k 2 21 3 k 13 k 22 9 k 2 12 k 4 33 k 2 4 k 1 1 3 k 1 So square integers can only be written in the form of 3 k or 3 k 1 . No square integer can be written as 3 k 2 . Take A k 1 and you get that 3 k 2 3 k 1 1 3 A 1 So you ' re right , no integer squared can be written in the form of 3 A 1 where A is an integer
