I'm not entirely sure if the focus of this question is more on marketing or the proof, but I can try to help a bit with the proof.
From what I can tell this is basically asking you to take a polynomial from column A, square it, and then add it to column B, and then simplify it while showing your work in order to create an identity. For example:
(x+y)^2 + (ax+b) =
x^2 + xy + +y^2 + ax+b =
x^2 + ax +y^2 + xy + b
Factor out an x from x^2 + ax and a y from y^2 + xy (you don't have to simplify it this way, I'm just doing it as an example)
x(x+a) + y(y+x) + b
Therefore, (x+y)^2 + (ax+b) = x(a+x) + y(y+x)
I can't really help with making a flier, but hopefully this helps
Find the unit rate ibthink
Answer:
-1 and 8/9
Step-by-step explanation:
Given:
Amount in the bank account = $1850
Monthly payment of can loan = $400.73
To find:
When would automatic payments make the value of the account zero?
Solution:
Craig stops making deposits to that account. So, amount $1850 in the bank account is used to make monthly payment of can loan.
On dividing the amount by monthly payment, we get

It means, the amount is sufficient for 4 payment but for the 5th payment the amount is not sufficient.
Therefore, the 5th automatic payments make the value of the account zero.
