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?

$6x^9 - 9x^6 - 48x^3 + 72$

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?
