The polynomial \(P(z)=i(z^2+1)\) has roots i and −i. What does this show?
Select the statement that follows from exactly the stated hypotheses
Conjugate-paired roots do not force every coefficient to be real when the leading scalar is unrestricted
Conjugate-paired roots force the leading coefficient to be real
A polynomial with a nonreal coefficient has no conjugate pair
The degree is one because the leading scalar is i
