 Author Comment/Response Gandalf Saxe 12/11/12 11:08am In: Factor[x^4 + 2 x^2 + 1] Out: (1 + x^2)^2 This factorizes the polynomial alright, but not in the form P(x)=(x-r1)^p2*(x-r2)^p2*...*(x-rk)^pk with the r's being roots and p's respective algebraic multiplicities. Is it possible to have Mathematica factor the polynomial x^4+2x^2+1 to (x+I)^2*((x-I)^2)? URL: ,
