Is there, or could there be, a "sum of squares" function for multivariate polynomials, which would rewrite an expression as a sum of squares, when possible? It might work like this: SumOfSquares[5 x^2 + 8 x y + 5 y^2 + 2 x z - 2 y z + 2 z^2] ---> (x + 2y - z)^2 + (2x + y + z)^2 Will Self email appreciated Sent via Deja.com http://www.deja.com/
