Proofs: Problem 3


You need to find specific concrete values for x, y, and z that make the equation false.

Go for small integer values, so the reader can easily verify that you're right.

Don't try to write a general argument or a general discussion of which values do/don't satisfy the equation. It's fine to explore this on your own, if you are interested. But don't put that into your answer. A simple concrete example is more deadly than a complex discussion.
