Given a polynomial equation p(x)=0, which expressions could be a pair of irrational roots of the equation?

please help I don't know how to solve this

    I just did one for you

    now if you want irrational roots
    of a quadratic, what is b^2-4ac = 5
    the sqrt 5 is irrational
    so both roots will be irrational
    now you could also use the rational roots theorem.
