Answer:

B. (x + 3) (x + 27)

Step-by-step explanation:

To factor the expression, you must split the middle term (18x) into two terms that can be added to get 18, and multiplied to get 81:

[tex]x^2 + 18x + 81[/tex]

[tex]x^2 +3x + 27x + 81[/tex]

Group:

[tex](x^2 +3x) (27x + 81)[/tex]

Take out GCF (Greates Common Factor):

x(x + 3) 27(x + 3)

(x + 27) (x + 3)
