I am struggling to find a way to create a maple graded question, that accepts a quadratic equation, but only in a specific form. For instance,

I need one question that only accepts as correct the standard form, another one that only accepts factored form, and other that only accepts vertex form.

Maple treats all three as equivalent (because they are) but how then can I restrict a student to use a particular form?

As a side question, I seem to have better luck when the response area is only used for the RHS of the equation. Whenever I try to have a maple graded response area that includes "y=" as part of the correct answer, I get all kinds of errors. Why is this?

Any help is greatly appreciated!
