Complex roots in CAS

[KeithB]

I tried using solve(-x^2-2x=5) but got [] as an answer. Is there a different command to get complex roots?

csolve(-x^2-2x=5)

It the toolbox -> CAS -> Solve you have 1 Solve 2 Zeros 3 Complex Solve 4 Complex Zeros

Thanks, don't know how I missed that, since I found solve()!

You can only use solve() by activating "Use i" to consider imaginary results.
