<u>The Difference of Squares Method for Factoring</u>
The expression:

Is a widely used method to factor binomials that are expressed as the subtraction of two perfect squares.
The condition for a binomial to be factored by using this method is that both terms must have an exact square root and they must be subtracted.
The last two choices are not valid because they are not a subtraction but an addition.
The first choice is not valid because none of the terms is a perfect square.
The second choice is correct. It can be factored as:

Answer:
r = 3072. A 4 is multiplied times each term to arrive at the next term. OR ... divide a2 by a1 to find the common ratio of 3072. :)

The solution in the attached figure
Answer:
see explanation
Step-by-step explanation:
product means to multiply, hence the product of 12 and k is
12 × k = 12k ( this is 84 means equal to 84 ), that is
12k = 84 ( divide both sides by 12 )
k = 7 ← is the solution
