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
Answer:
x=14
Step-by-step explanation:
g(x) = 2(x − 4)
Let g(x) = 20
20 = 2(x − 4)
Divide each side by 2
20/2 = 2(x-4)/2
10 = x-4
Add 4 to each side
10+4 = x-4+4
14 =x
You would multiply 62 1/4 and 4. Which you cant do that so you would have to make it into a inproper fraction so that will be 249/4 times 4/1 then you can multiply which your answer would be 996 /4 and then in simplest form would be 249/1= 249
