Question

Which of the following is the correct factorization of the polynomial below?

x2-18
O A. (x+3)(x-6)
O B. (x-3)(x + 6)
O C. (x+3)(x2 - 4x+6)
D. The polynomial is irreducible.

Answer 1

D. The polynomial is irreducible

Explanation:

This polynomial is unfactorable. x² and 18 share no common factors. It is already in simplist form.

hope this helps :)
