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

$\displaystyle (x-y)(x+y)(y^4+x^2y^2+x^4),$

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.
