If you need further assistance write back. Penny John wrote back i'm afraid that i'm still not completely understanding John, The next step is the factor theorem which says that if a is a root of a polynomial p(x) then (x  a) is a factor of the polynomial. Thus if a is a root of p(x) then p(x) = (x  a)q(x) for some polynomial q(x). Penny
