Answer 1

The answer is in the photo I hope it helps you get it solved !

Answer 2

y -1
__________________________
y^3+1 / y^4 - y^3 + 2y^2 + y - 1
y^4 + y
----------------------------------------
-y^3 + 2y^2 - 1
-y^3 -1
---------------------------
2y^2
2y^2
The quotient is y - 1 with a remainder -------------
y^3 + 1
