Real = Real
Complex = Complex


Every number possible lies within the subset of complex numbers though, does it not? Then there is a real part and imaginary part.

When it says real root, doesn't it just mean a solution without an i term?

And complex means a real and imaginary?
and imaginary is just an i component?
