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?

but complex number is defined as a + bi: a, b ∈ R .....
b can be zero.. right?...

When they ask for complex roots. Your answer may be real.

When they ask for real roots. Your answer must be real.
