Solve $a^2+b^2+c^2+d^2+2ab+2bc+2cd-2ca-2ad-2db=N^2$

Web$ a^2 + b^2 + c^2 \ge ab + bc + ca\\ \Longleftrightarrow \frac12(2a^2 + 2b^2 + 2c^2 - 2ab - 2bc - 2ca) \ge 0\\ \Longleftrightarrow (a^2 - 2ab + b^2) + (b^2 - 2bc + c^2) + (c^2 - 2ac + a^2) \ge 0 \\ \Longleftrightarrow (a-b)^2 +(b-c)^2 +(c-a)^2 \ge 0 $ which is obviously true.
