The equation described in 2 equals 0,

In 8, you got equation (1) and your neighbor got (2). For what values of a and b(a and b are distinct), for at least 1 of the solutions are the same?

I have three quotes in case you are thinking of revealing anything you think you know about me:

Cobbie Bean, Cobbie Bean, never tell what you have seen.

Omerta - The code of silence.

He who is deaf, blind, and silent will live a hundred years in peace.
