Which of the following is the correct factorization of the polynomial below?
x - 18
A. (x+3)(x-6)
B. (x-3)(x + 6)
C. (x+3)(x2 - 4x+6)
D. The polynomial is irreducible.
SUBMIT
D. The polynomial is irreducible is the correct answer because x and -18 don't share anymore common factors for it to factorized/simplified, so x - 18 is as far as it can get.
