Show a polynomial of degree n has at most n distint roots

    If F is a field, how do we prove that a non-zero polynomial with coefficients in F and of degree n has at most n distinct roots in F?

    have you tried induction on the degree of the polynomial?

    e.g. can you do it for degree one polynomials?
