Example 2: Roots of a polynomial

Another purpose of using this feature is to provide the student with the steps they should have followed to answer the question correctly. Let's consider the following case:

You can add dynamic feedback to the question based on the student's answer. For example, in this question, you could display the student's procedure to solve the problem. Moreover, you can also explain why the provided answer is not appropriate.

To do so—as in the previous example—you must write the parameter answer = 0 in your CalcMe algorithm. From that point on, the student's answer will be stored in a variable called answer. For the customized feedback example just mentioned, you’ll need to access the two answers given by the student and calculate the value of the polynomial at those points. The algorithm must end with this:

Then, you have to add an answer blank for the incorrect answers and apply the customized feedback to it. Pay attention to the notation used!

Finally, you have to add the general feedback that shows the procedure to solve the problem.
