Question:
Factor 
(8 - x)(8 - x)
(8 + x) (8 - x)
(X + 8)(x-8)
Answer:
Option B:
is the factor
Explanation:
Given that the expression is 
We need to find the factor of the given expression.
Let us rewrite the expression as 
Since the expression is of the form
, let us use the identity 
where a = 8 and b = x
Substituting the values in the identity, then the expression can be written as

Thus, the factor of the expression is 
Hence, Option B is the correct answer.
n=2
8+8(8-n)=40+8n (distribute 8 through the parenthesis)
8+64-8n=40-8n (add the numbers)
<em>72-</em>8n=40+8n (move the variable to the left side and change its sign)
<em>72</em><em>-</em>8n+8n=40
-8n+8n=40<em>-72</em> (connect like terms)
-16n = -32 (divide both sides by -16)
<u><em>n=2</em></u>
