Both results are what you should expect. sage: type((A^2+B).factor()+(B^2).factor()) <type 'sage.rings.polynomial.multi_polynomial_libsingular.MPolynomial_libsingular'> Hence, in your first example, you list a polynomial. The result is a list of pairs (c,m), where c is a coefficient and m is a monomial. sage: type((A^2+B).factor()) <class 'sage.structure.factorization.Factorization'> Hence, in your second example, you concatenate two lists that are obtained from two factorizations. When you list a factorisation, you obtain a list of pairs (x,d), where x is a factor and d is the exponent of that factor in the factorisation.
