A polynomial function with a leading coefficient of 1 and multiplicity 1 for each factor has the
following roots: x-2 x-(1+ sqrt5 x+3i

Another factor of the polynomial is:

1. x+2
2. x-(1-sqrt5) - right answer
3. x-sqrt5

The complex conjugates theorem states that another factor of the polynomial is:

1. 3ix
2. x+2
3. x-3i -right answer

What is the degree of the polynomial?

5- right answer
