All of them. Real numbers are a subset of complex numbers.
The complex numbers are a field.
Gerolamo Cardano is an Italian mathematician who introduced complex numbers. Complex numbers are those that can be expressed in the form of a+bi where a and b represent real numbers.
The 16th century Italian mathematician, Gerolamo Cardano was the first to use imaginary and complex numbers in his work on cubic equations.
Complex numbers are the square roots of negative numbers. i.e. root -1 = i
yes it does
electrical engineers and quantum mechanics use them.
I suggest you read the Wikipedia article con complex numbers, specifically the section "Applications". One example is electrical engineering: in the case of AC, it helps to express all voltages, currents and impedances (equivalent of resistances) as complex numbers.
Yes, many

I'm not sure about how to use complex numbers to do this, but I've posted a link to a pretty neat website about Synthetic Division.
when you multiply it with another polynomial
using contraction and expansion
Complex numbers are a proper superset of real numbers. That is to say, real numbers are a proper subset of complex numbers.
No. Complex numbers is the highest set of numbers you can go, and there are no sets outside of complex numbers.
Yes. Integers, Real Numbers, and even Complex Numbers can as well.
