Answer:
The answer to your question is: d
Step-by-step explanation:
x³ - 18
a) (x + 3)(x - 6) The polynomial given do not have the structure x² - mx +
+ c, so this option is incorrect
b) (x - 3)(x + 6) This polynomial do not have the structure x² - mx + c.
c) (x + 3) (x² - 4x + 6) The polynomial given is not a difference of cubes.
d) The polynomial is irreducible because 18 does not have a cubic root.
