Step-by-step explanation:
The complete factorized form for the given expression is 
<u>Step-by-step explanation:</u>
Step 1: Given expression:

Step 2: Trying to factor as a Difference of Squares
Factoring 
As we know the theory that the difference of two perfect squares,
can be factored into (A+B) (A-B)
from this, when analysing, 81 is the square of 9,
is the square of
. Hence, we can write the given expression as,

By using the theory, we get

Again, we can further factorise the term 
is the square of
. Therefore, it can be expressed as below

Now, we can not factorise further the term
. Because it will come as
(3 is not a square term). Thereby concluding that the complete factorisation for the given expression is 
The probability of rolling an even number on a six sided die is 1/3.
