For this case we have the following data:
- Polynomial identity: [tex](x-y) ^ 2 = x ^ 2-2xy + y ^ 2\\[/tex]
- We want to show that: [tex]8^2 = 64[/tex]
Let's suppose:
[tex]x = 8\\\\y = 0\\[/tex]
Substituting in the identity we have:
[tex](8-0) ^ 2 = 8 ^ 2-2 (8) (0) + 0 ^ 2\\\\(8) ^ 2 = 64-0 + 0\\\\8 ^ 2 = 64\\[/tex]
Thus, we can use [tex](x, y) = (8,0)[/tex] to prove the identity.
Answer:
[tex](x, y) = (8,0)[/tex]
