Here's how I've been going about it.

4x^4 - 3x^2 + x + 2 = (2x + 3)(ax^3 + bx + c) + R

Then after expanding and collecting like terms, I have:

2ax^4 + 3ax^3 + 2bx^2 + (2b+2c)x + 3c + R

And it's here that I get stuck. The problem here is that I don't know how to go on. What for example do I do with the x^3 bit?

Many thanks
