Question 79799
Polynomial functions with rational coefficients always have irrational and complex zeros in conjugate pairs.  That is a fancy way of saying that if you have a zero of {{{sqrt(7)}}},then you also have a zero at {{{-sqrt(7)}}}.  If you have a zero at {{{4-2i}}}, then you also have a zero at {{{4+2i}}}.
