The term in parentheses is a perfect square trinomial that can be expressed as follows:
(x²  12x + 27) → (x  3)*(x  9)
Answer:
(2) (x  3)*(x  9)
For better understanding, follow the example and the annex:
The square of the difference of two terms
Following the criteria of the previous item, we have: (ab)² = (ab).(ab)
Where a is the first term and b is the second.
When we develop this product, using the distributive property of multiplication.

Hi, This do isn't difficult.
Look to the options:
Let's to the 1 Example:
1:
(X+3).(X 9)
Do the product one by one.
x.x + x.(9) +3.x+3.(9)
x^2 9x +3x 27
x^2 6x 27
Looking to the given equation
This is wrong
__________
Let's to the second example
2:
(X3).(X9)
Apply the product one by one
X.X + X.(9) 3.(x)3.(9)
x^2 9x 3x +27
x^2 12x + 27
OooH, then this would be your answer.
The 2 option.
