    Huh? Are you having trouble with the Web site itself, or with the factoring? Why don't you post your work so that we can check it?

    Okay, now that I have looked at it, it does seem a bit puzzling.

    I do not see how you could fit the full answer into only 22 characters. You could put it in as

    (x-y)(x+y)(y^4+x^2y^2+x^4),

    but then you would not be following the instructions to factor completely. Perhaps this you should take up with your instructor?

    For the second one, you should be able to fit the full answer (though with one space left over; I am not sure if that is a problem).

    Edit: By the way, that system seems needlessly inconvenient and cumbersome. I would complain.

    Question: X^3 + 1/8

    Answer: (x + 1/2)(x^2 - 1/4 + X 1/2)

    That does not sit well with me. The problem says to factor completely, but the "correct" answer can be factored further into

    (x-y)(x+y)(x^2-xy+y^2)(x^2+xy+y^2).

    Again, I would take this up with the instructor.

    Question: X^3 + 1/8

    Answer: (x + 1/2)(x^2 - 1/4 + X 1/2)
    You have your signs backwards. If you check by multiplying it out, you can see that the answer is incorrect.
