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!
