Question

You must: 
•	Label and display your new polynomial identity 
•	Prove that it is true through an algebraic proof, identifying each step 
•	Demonstrate that your polynomial identity works on numerical relationships 
WARNING! No identities used in the lesson may be submitted. Create your own. See what happens when different binomials or trinomials are combined. Below is a list of some sample factors you may use to help develop your own identity. 
•	(x – y) 
•	(x + y) 
•	(y + x) 
•	(y – x) 
•	(x + a) 
•	(y + b) 
•	(x2 + 2xy + y2) 
•	(x2 – 2xy + y2) 
•	(ax + b) 
•	(cy + d)

How about
$$(x+y)^{2}= x ^{2}+ 2xy + y ^{2}$$
