The correct answer is A). None
Step-by-step explanation:
The given quadratic polynomial has 3 roots and some of roots are x= and x=6+i
It is necessary to note that one of the roots is a complex number and root of complex number always in pair of the conjugate to each other.
Since x=6+i
Conjugate of (6+i) is (6-i)
<em>Therefore, (6-i) is 3rd required root of a polynomial </em>
<em>The correct answer is A). None</em>
