I have a question where I have to divide:

x^4-2x^3-3x^2+11x+3 by x^2-4

So doing by long division I have got as far as:

Sorry about it being hard to read I didn;t know how to do it by typing it.

Anyway in all the example I have of doing this the power of the second term (-2x^3 and 4x^2) has been the same but in this one it is not. Have I made a mistake or am right so far?

If I am right so far how do I take it forward?
