Maybe that is a printing mistake?

My teacher told to assume (n-k) as a zero of the polynomial

hi Agnishom,

I suggest you check the question.  If it started " x + k is a factor....." then that result can be found using Nehushtan's method.

If we maintain (n-k) then since both quadratics must have factors of the form (x - a) and (x - b) that suggests x = n or x = k.  The problem then de-generates and certainly doesn't give that result.

That is the problem (n-k) is the factor

If
