I'd like to find field-elements a,b,c such that
a(x^2+y^2)+b(xy+zx)+c(xyz)==0, if they exist (I know they do)''
so that Sage returns (a,b,c)=(0,0,0). That seems to be an easy matter if one can traduce the polynomial identity into a vector space identity. I proved to be unable to do so.
I've to say that my polynomial identities are quite more cumbersome and include up to 7 variables so working them by-hand is almost impossible in a finite ammount of time or patience.AngelSun, 27 May 2012 11:53:59 +0200https://ask.sagemath.org/question/9006/
