(CAS and Home) I get only the expression unchanged, like user rombva, no matter what settings I make. Many thanks in advance! Terribly sorry... The screen shot I posted above was apparently obtained using a different firmware version, possibly a beta version which didn't say "BETA" in the top corner. All the recent firmware versions (I think!) return x^4+1 for an input of factor(x^4+1), as you and rombva said. My mistake! Sorry!

RE: factor(x^4+1) and partfrac(1/(x^4+1)) - Tim Wessman - 10-24-2019 09:59 AM Just an FYI, the CAS 1.5.0 version does do what you want with default settings I think. Take a look at the public beta just made available if you want. https://www.hpmuseum.org/forum/thread-13855.html
