To factor x^4+4 I do this: I add and subtract 4x^2 to get x^4+4+4x^-4x^2=(x^2+2)^2-4x^2=(x^2+2+2x)(x^2+2-2x) I CAN do in this way, but how can Mathematica do it automatically? Somebody knows about skills to factor polynomial like previous and like x^4+x^2+1? bye and thanx in advance Raffaele -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG
