Solution Steps

To solve the problem using synthetic division, we need to follow these steps:

  1. Identify the coefficients of the polynomial x3+1x^3 + 1.
  2. Use the root of the divisor x1x - 1, which is 11, for synthetic division.
  3. Perform the synthetic division process to find the quotient and the remainder.
Step 1: Identify Coefficients

The polynomial x3+1x^3 + 1 can be expressed in terms of its coefficients as follows: Coefficients=[1,0,0,1] \text{Coefficients} = [1, 0, 0, 1] This corresponds to 1x3+0x2+0x+11x^3 + 0x^2 + 0x + 1.

Step 2: Perform Synthetic Division

Using the root of the divisor x1x - 1, which is 11, we perform synthetic division. The process yields the following results:

  • The first coefficient is 11.
  • The next coefficients are calculated as follows:
    • 0+11=10 + 1 \cdot 1 = 1
    • 0+11=10 + 1 \cdot 1 = 1
    • 1+11=21 + 1 \cdot 1 = 2

Thus, the synthetic division results in: Quotient=[1,1,2] \text{Quotient} = [1, 1, 2] and the remainder is: Remainder=2 \text{Remainder} = 2

Step 3: Express Quotient and Remainder

The quotient can be expressed as: x2+x+2 x^2 + x + 2 and the remainder is: 2 2

Final Answer

The quotient and remainder from the division of x3+1x^3 + 1 by x1x - 1 are: Quotient: x2+x+2 \text{Quotient: } \boxed{x^2 + x + 2} Remainder: 2 \text{Remainder: } \boxed{2}
