    FOIL method

    Use the FOIL method to find the product
    (6x^3 - 9)(x^6 - 8)
    (6x^3*x^6)+(6x^3*-8)-(9*x^6)-(9*-8)
    6x^9-48x^3-9x^6-72
    Now I am confused have I done right?

    Is that all that can be done to this problem? I thought that I could continue with simplifying the coeffients of X and the exponents?
