Most of the time, the best way to create a regeneratable version of a question is to start with an existing question - something that is already "doing the job" that you want done. For this example we are going to use a simple trinomial factorisation question.
At the moment, this is a "static" question. We want to add parameters to the question so it can regenerate itself.
HINT: It is often best to start with the answer and work back to the question. We will be using this idea.
We are assuming that the equations have previously been written with FX Equation.
