The polynomial x^4+1 may be rewriten as a product of polynomials over the field of reals (for example, HP 50g can factorize it). What's wrong with HP Prime's factorization in the real mode in this case? Hello Joe, can you please post your other settings? (CAS and Home) I get only the expression unchanged, like user rombva, no matter what settings I make. Many thanks in advance!
