Answer:
2y^3 + 2y^2 - y - 1
Step-by-step explanation:
6у^5 + 4y^4 - 3у^3-1 by y^2 - y + 1:-
We need to write the first expression as
бу^5 + 4y^4 - 3у^3 + 0y^2 + 0y - 1 (inserting all the missing degrees).
So we have:
3y^2 - y + 1 ) бу^5 + 4y^4 - 3у^3 + 0y^2 + 0y - 1 ( 2y^3 + 2y^2 - y - 1
6y^5 - 2y^4 + 2y^3
6y^4 - 5y^3 + 0y^2
6y^4 - 2y^3 + 2y^2
-3y^3 - 3y^2 + 0y
-3y^3 + y^2 - y
- 3y^2 + y - 1
- 3y^2 + y - 1
