Answer.

Answer= B

Step-by-step explanation:

For the roots to be right, you will have answer zero if you sub them for x.

A.

(we first try to sub -6 for x in the polynomial)

=

= -384

(this is not equal to zero (-384≠0) so the first polynomial is wrong)

B.

(we do the same as above but in this polynomial)

=

=0

(this is equal to zero but that does not mean it is right because all the roots need to equal zero when you sub them. So now we try 1 and 4)

For (x=1):

=

=0

(because this is zero we will complete and try the root 4)

For (x=4):

=

=0

(this is means that the answer is B because all the roots are equal to zero when you sub them for x)
