Assuming that you're using X and x to mean the same thing, then yes, you wouldn't include the undefined.
The possible solutions are x = {2, 3, 4}.
Hey guys,
I've been working on some math and have hit a cement wall containing bits of broken glass. Allow me to give you the gist of it. Here is the problem: (x-2)(x-3)(x-4)2^X=0. Now I have found the following answers {2, 3, 4, and undefined}. What I was wondering is because one of the values of x is undefined is the answer entirely undefined or is it {2, 3, 4} omitting the {undefined}?
