    Post Rational Zero Theorem

    Morning Forum does anyone have a opinions on the following question ?

    If using the Rational Zero Theorem suggests that there are no positive or negative rational roots for a polynomial function of degree 4 with integer coefficients, must all the roots be irrational? Explain.

    For instance x^4+1=0
