Answer:
C.
Step-by-step explanation:
We want to find the equation of a polynomial the following properties;
i. Leading coefficient is 1
ii. roots (7 + i) and (5 – i) with multiplicity 1
Recall the complex conjugate properties of the roots of a polynomial.
According to this property, if
is a root of a polynomial, then the complex conjugate,
is also a root.
This means that:
(7 - i) and (5 + i) with multiplicity 1 are also roots of this polynomial.
The complete set of roots are:
Therefore the polynomial is:
The correct choice is C.
