There is a polynomial which, when multiplied by x^2 + 2x + 3, gives 2x^5 + 3x^4 + 8x^3 + 8x^2 + 18x + 9. What is that polynomial? 

(Give your answer as a polynomial in which the terms appear in order of decreasing degree. In other words, "x^5 + x + 2" is a valid answer, but "2+x^5+x" is not.)

This sounds like your homework. It is difficult to explain the process used to solve this, I think it's called "synthetic division". I don't like simply providing the answer, either. Have you not studied this in class?
