Hi all, I followed the instructions on this page:
to create a question using the Equivalence Reasoning input type. I followed the whole thing faithfully and was able to get the first part correct (before "More Specific feedback". Basically as long as I enter an algebraically equivalent expression a tick will appear. When answer is submitted, it will accept any algebraically equivalent expression.
However, when I went on to the next part, which is to expect an expression that is expanded completely, by adding a second node, I was unable to make it work. It still accepts a factorized expression such as the question itself (x+2)^3 as a valid answer.
Can someone let me know what I did wrongly? Attached are screenshots of my settings.
