It *is* a ternary quadratic form once you homogenize with a 3rd variable z.
Finding rational points on plane conics (which is what this is) has
advanced substantially in the last few years. My paper with Rusin
(Mathematics of Computation, 72 (2003), no. 243, pages 1417-1441.)
works well for diag
Hi Utpal,
Does the Hasse-Minkowski theorem apply for a non-quadratic form like
mine?

There is not always a solution. Whether or not there is a solution is
the contents of the Hasse-Minkowski theorem. I couldn't find a
function in sage that immediately tells you whether there is a
rational solution. There is a function that tells you whether there is
a local solution at a prime p,
