The evaluation type eval polynomial can be used to check (multivariate) polynomials. It does not have automated feedback itself, but instead the evaluation type fb polynomial can be used to give automated (positive or negative) feedback on the student’s answer.
Evaluation type: eval polynomial
The Definition field of this evaluation type should have a (multivariate) polynomial.
Example:
When this evaluation type is used in a Solution rule, the evaluation type fb polynomial can be used in positive or negative feedback to give automated feedback on the student’s answer.
Evaluation type: fb polynomial
This evaluation type can only be used in (positive and negative) feedback when a solution rule is defined that uses eval polynomial. The Definition field should contain the name of the desired polynomial form. The possible polynomial forms are:
free
Polynomial can be in any form. Performs no checks in positive or negative feedback.basic
Performs basic checks on the student’s answer.
Checks when used in positive FB  Checks when used in negative FB 
 Same as in positive feedback 
expanded
Polynomial should be in expanded form.
Checks when used in positive FB  Checks when used in negative FB 


factored_expanded
Polynomial should be in factored form.
Checks when used in positive FB  Checks when used in negative FB 


factored_expanded_count
Checks when used in positive FB  Checks when used in negative FB 


factored_basic
Checks when used in positive FB  Checks when used in negative FB 


factored_basic_count
Checks when used in positive FB  Checks when used in negative FB 


Examples of feedback
The solution rule that is used for these examples is:
Example 1 (basic
, negative feedback)
Example 2 (expanded
, positive feedback)
