Question 1028617: I have this question on my assignment:
"Create two different rational polynomial expressions with the following constraints:
-one expression is undefined when x = 4
-the other is undefined when x = ‒2 or 0.
Then, rewrite both as equivalent expressions, with a common denominator."
I think I understand how polynomial expressions expressions work I just can't figure out how to work backwards only knowing constraints. I really have no idea where to ever start.

Division by zero is undefined so,
is undefined when .
You can just add more factors to the denominator,
is undefined when and .
So then use the common denominator,

and similarly,
