Answer:

Final answer is A. 9(3x+1)(3x-2).

Step-by-step explanation:

Given expression is 81x^2-27x-18.

81x^2-27x-18

=9(9x^2-3x-2)

We can factor that by splitting middle term into two parts then do grouping as shown below:

=9(9x^2-6x+3x-2)

=9(3x(3x-2)+1(3x-2))

=9(3x+1)(3x-2)

Which correctly matches with choice A. 9(3x+1)(3x-2).

Hence final answer is A. 9(3x+1)(3x-2).
