I need help finding complex roots
Hi all. I'm very new to HP Prime and I've tried to do my research about my question, but everything I try doesn't work.
I'm trying to find roots of a Quadratic formula. I can't find out how to do it. Example: x^2+2x+5=0 this is the answer i'm hoping to see from the calculator: x = -1 + 2i or x = -1 - 2i I have tried Toolbox->Polynomial->Find Roots (and it gave me -2 as an answer?) Toolbox->Solve->Solve, Zeros, Complex Solve, Complex Zeros Nothing is giving me the answer I want. What am I missing? Why would proot only give me one answer? Thanks so much for your time! |
