Complex roots in CAS - KeithB - 04-20-2017 03:24 PM I tried using solve(-x^2-2x=5) but got [] as an answer. Is there a different command to get complex roots? RE: Complex roots in CAS - Tim Wessman - 04-20-2017 03:33 PM csolve(-x^2-2x=5) It the toolbox -> CAS -> Solve you have 1 Solve 2 Zeros 3 Complex Solve 4 Complex Zeros RE: Complex roots in CAS - KeithB - 04-20-2017 03:52 PM Thanks, don't know how I missed that, since I found solve()!
