Marshall uses the polynomial identity (x−y)^2=x^2−2xy+y^2 to show that 8² = 64.
vladimir2022 [97]

For this case we have the following data:

  • Polynomial identity: (x-y) ^ 2 = x ^ 2-2xy + y ^ 2\\
  • We want to show that: 8^2 = 64

Let's suppose:

x = 8\\\\y = 0\\

Substituting in the identity we have:

(8-0) ^ 2 = 8 ^ 2-2 (8) (0) + 0 ^ 2\\\\(8) ^ 2 = 64-0 + 0\\\\8 ^ 2 = 64\\

Thus, we can use (x, y) = (8,0) to prove the identity.

Answer:

(x, y) = (8,0)
