Question 79799: suppose that a polynomial function of degree 5 with rational coefficients has 3, sq root of 7, 4-2i as zeroes. find the other zeros Answer by rapaljer(4671) (Show Source):
You can put this solution on YOUR website! 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 ,then you also have a zero at . If you have a zero at , then you also have a zero at .
