the second example on the page is incorrect. I tried to see if I could edit it, but I got a you don't have permission to edit message.
\( 3x^2 + 5xy + 2y^2 = (3x+2y)(x+y) \), not \( (3x+y)(x+2y) \).
I followed the advice "if you are not sure where to post, post it here." Sorry if this is not the right place to report this.
Showing a formula as a choice
In this example, we want the student to demonstrate they know how to correctly factor out a binomial equation. We want every student to have a unique problem to solve.
For example the teacher enters the question as:
Given the binomial equation 3x2+5xy+2y2, where x = {A} and y={B} how would you simplify it before solving it?
The correct choice would be written:
This polynomial can be reduced to (3*{A}+{B})({A}+2*{B}).
This choice would display as:
This polynomial can be reduced to (3+2)(1+4).
