what must be multiplied to 4x^4 - 2x^3 - 6x^2 + x - 5 so that the result is exactly divisible by 2 x^2 + x - 1

Hey Mate..
Step-by-step explanation:
Lets divide (4x4 - 2x³ - 6x³ + x - 5) by (2x² + x – 1) as shown.
2x² + X - 1 ) 4x∧4 - 2x³ - 6x² + x - 5 ( 2x² - 2x - 1
4x∧4 - 2x³- 2x²
¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬
- 4x³ - 4x² + x
- 4x³ - 4x² +2x
+ - -
¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬
- 2x² - x - 5
-2x² - x - 1
¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬
-6
¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬
Hence (−6) should be subtracted from (4x4 − 2x3 − 6x2 + x − 5) so that the resulting polynomial is exactly divisible by (2x2 + x – 1).
