Given, 2x^4-9x^3+5x^2+3x-8 by x^2-4x+1
x^2 - 4x + 1) 2x^4 - 9x^3 + 5x^2 + 3x - 8 ( 2x^2 - x + 1
2x^4 - 8x^3 + 2x^2
---------------------------------------
x^3 + 3x^2 + 3x - 8
x^2 + 4x^2 - x
-----------------------------------------
x^2 + 4x - 8
x^2 + 4x - 1
------------------------------------------
- 7
verification of division algorithm :
= (x^2 - 4x + 1) * (2x^2 - x + 1) - 7
= 2x^4 - x^3 - x^2 - 8x^3 + 4x^2 + 4x + 2x^2 - x - 1 - 7
= 2x^4 - 9x^3 + 5x^2 + 3x - 8.
Hope this helps!
