How are the factors of a polynomial related to the xintercepts of a polynomial? How do you find the xintercepts given the factors?

You have to factor the polynomial. If for instance you get (x3)(x+2), then your x intercepts are where you take each to equal 0. (x3)= 0 so x = 3; and (x+2) = 0 so x = 2. The x intercepts are the opposite sign of the values of the constants in each binomial.
