we have that

(x^4 + 4x^3 – 5x^2 + x - 3)/ (x^2 + x -3)

x^2+3x-5

-x^4-x^3+3x^2

---------------------------------

3x^3-2x^2+x -3

-3x^3-3x^2+9x

-----------------------

-5x^2+10x -3

5x^2+5x -15

--------------------

15x-18

therefore

(x^4 + 4x^3 – 5x^2 + x - 3)=(x^2 + x -3)(x^2+3x-5)+(15x-18)
