Determine which polynomial has (x – 9) as a factor.

option D

Step-by-step explanation:

(x-9) is a factor

x-9 =0 so x=9

now we plug in 9 for x  and see which polynomial gives us remainder 0

A. x^2 - 6x +9 = 9^2 - 6(9) + 9 = 36

Remainder = 36 so (x-9) is not a factor

B) x^2 + 16x + 63= 9^2 + 16(9) + 63 = 288

Remainder =288 so (x-9) is not a factor

C) x^2 + 14x + 45= 9^2 + 14(9) + 45 = 252

Remainder = 252 so (x-9) is not a factor

D) x^2 - 12x + 27= 9^2 -12(9) + 27 = 0

Remainder = 0 so (x-9) is a factor

1/3 + 1/5 = 8/15.
