Suppose the roots of a polynomial are 4, −7, 8, and 9. Which choice is a factor of the polynomial?

A) (x + 4)
B) (x + 8)
C) (x − 7)
D) (x − 9)

Answer:

D) (x − 9)

Step-by-step explanation:

x - 9 = 0

therefore x = 9

Polynomials A) (x + 4), B) (x + 8) and C) (x -7) won't give you the roots 4, −7, 8. They will produce -4, -8 and 7.

Hence, D) (x - 9) is the correct answer.
