Please be aware! Xronos is very good at making sure the factored polynomial you have entered is the same polynomial. It is less reliable to know if you have entered a fully factored version of that polynomial. To be sure that your factored version is fully factored, you should check two things:
  • Every factor is degree 1 or degree 2 polynomial (a linear expression or a quadratic).
  • If the factor is a quadratic, then the discriminate () must be negative. If it is Zero or positive, then that term can be factored further and you should try to do so.

Note: This is using an experimental factoring validator. If you verified that your answer should be correct and Xronos won’t take it, please email your instructor to see if there is a problem.
