Find if the second polynomial is a factor of the first polynomial.
$ 8 x^{4}+10 x^{3}-5 x^{2}-4 x+1,2 x^{2}+x-1 $
Let us divide and see if the remainder is zero or not
2x2 + x -1)8x4+10x3- 5x2-4x+1(4x2+3x-2
8x4 + 4x3 -4x2
--------------------
6x3 - x2 -4x
6x3 + 3x2 -3x
--------------------
-4x2 - x + 1
-4x2 -2x +2
-----------------
x -1 Remainder
Since the remainder is NOT a zero, the second polynomial is NOT a factor of first polynomial.
