A)none
b)7
c)6i
d)i-6
e) - square of 7
( look at the picture better)

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)

Therefore, (6-i) is 3rd required root of a polynomial

The correct answer is A). None

x=half
