Since the first polynomial is given to be a factor of the second, you can divide the second by the first and then find P, Q and R such that all of the coefficients of the remainder come out to be 0. I get 15 for the final answer. camilus 09-10-07, 03:17 PM awsome. thanks for the confirmation. I got 15 as well. |
