Solution

Synthetic Division:

Dividend = `y^3 - 3y^2 + 5y - 1`

Divisor = y - 1

Opposite of −1 = 1

The coefficient form of the quotient is (1, −2, 3). 
∴ Quotient = y− 2y + 3 and Remainder = 2 

Linear Method:

`y^3 - 3y^2 + 5y - 1`

`= y^2 (y - 1) + y^2 - 3y^2 + 5y - 1`

`= y^2 (y - 1) - 2y (y - 1) -2y +5y - 1`

`= y^2 (y - 1) - 2y (y - 1) + 3(y -1) + 3(y - 1) +3 - 1`

`= (y - 1) xx (y^2 - 2y + 3) + 2`
