first you need to divide the numerator by denominator
2x³-x²-4x-2
______________
(2x-1) | 4x⁴+0x³-9x²+0x+2
| 4x⁴-2x³
----------------------
2x³-9x²
2x³-x²
----------------------
-8x²+0x
-8x²+4x
----------------------
-4x+2
-4x+2
---------------------
0
---------------------
therefore,
=> (2x-1) (2x³-x²-4x-2)/ (2x-1)
÷(2x-1)
=> (2x³-x²-4x-2) is the answer
