Answer 2

Answer:

the formula is (x+a)(x+b)=x^2+(a+b)x+ab

step by step explanation:

Multiply  (x-8)  by  (x-8)  

The rule says: To multiply exponential expressions that have the same base, add up their exponents.

In our case, the common base is  (x-8)  and the exponents are :

         1, as  (x-8), is the same number as  (x-8)1  

and   1, as  (x-8)  is the same number as  (x-8)1  

The product is therefore,  (x-8)(1+1) = (x-8)2  

Final result :

 (x - 8)2
