Answer:
B. The fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. The roots are x=3±i√11/2 .
Step-by-step explanation:
We know that,
Fundamental theorem of algebra states that ' a polynomial of degree n will have n number of roots'.
Since, the polynomial
has degree 2, so it will have 2 roots.
We know that the polynomial
has roots given by
.
So, the roots of polynomial
will be,

i.e. 
i.e. 
i.e. 
i.e. 
Hence, the roots are given by 
So, option B is correct.
