I am going to assume you are asked if 3x^{3}  3x  3 is divisible by 3x + 6. If 3x^{3}  3x  3 is divisible by 3x + 6 then there is a polynomial p(x) so that
You could find p(x) by long division if you wished, but in stead examine at the equation above. Each side is divisible by 3 so it simplifies to
What is the value of the left side when x = 2? Penny
