e.g.
sage: x,y = var('x,y'); f1(x,y) = (x + y)^2 ; f2(x,y) = x^2 + 2*x*y + y^2 ;
diff = (f1 - f2 + 1).factor(); print "diff = ",diff
1
from above will become simply
sage: R.<x,y> = QQ[]; f1 = (x + y)^2 ; f2 = x^2 + 2*x*y + y^2 ; f1 - f2

Whether you can get away with QQ (rational coefficients) is of course
dependent upon your data...
