Answer:
Quotient=y2 −2y+3
Remainder = 2
Step-by-step explanation:
Synthetic Division :
Divided = y3 −3y2+5y−1
Divisor = y-1
Opposite of -1 = 1
The coefficient from of the quotient is (1,-2, 3)
∴Quotient= y2 −2y+3
Remainder = 2
Linear Method :
y3 −3y2+5y−1 =y 2
(y−1)−2y(y−1)+3(y−1)+3−1
=(y−1)×(y2 −2y+3)+2
