Answer:


(x^(2) +x+1)(x-1)+2

Explanation:

The synthetic division can be used to divide a polynomial function by a binomial of the form x-c, determining zeros in the polynomial.

step 1: Establish the synthetic division, placing the polynomial coefficients in the first row (if any term does not appear, assign a zero coefficient) and to the extreme left the value of c.

1 | 1 0 0 1

step 2: Lower the main coefficient to the third row.

1 | 1 0 0 1

1

Step 3: Multiply 1 by the main coefficient 1.

1 | 1 0 0 1

1

1

step 4: Add the elements of the second column.

1 | 1 0 0 1

1

1 1

step 5: Then repeat step 4 until the constant term 1 is reached.

1 | 1 0 0 1

1 1 1

1 1 1 2

step 6: Enter the quotient and remainder

quotient:
x^(2) + x + 1

remainder: 2

Solution:
x^(2) + x + 1
(x+1)  + 2
