Math Problem Statement

Use synthetic division to divide x^3 + x^2 - 4x + 3 by x - 2.

Solution

To divide x3+x24x+3x^3 + x^2 - 4x + 3 by x2x - 2 using synthetic division, we follow these steps:

  1. Write down the coefficients of x3+x24x+3x^3 + x^2 - 4x + 3: 1,1,4,31, 1, -4, 3.
  2. Since we're dividing by x2x - 2, the number we use in synthetic division is 22.

Let's proceed with the synthetic division:

Synthetic Division Steps:

  1. Write down the coefficients: 1,1,4,31, 1, -4, 3.
  2. Bring down the first coefficient 11 as it is.
  3. Multiply this 11 by 22 and write the result (22) below the next coefficient:
    • The second column becomes 1+2=31 + 2 = 3.
  4. Multiply 33 by 22 and write the result (66) below the next coefficient:
    • The third column becomes 4+6=2-4 + 6 = 2.
  5. Multiply 22 by 22 and write the result (44) below the last coefficient:
    • The fourth column becomes 3+4=73 + 4 = 7.

Result:

The bottom row represents the coefficients of the quotient and the remainder:

  • Quotient: x2+3x+2x^2 + 3x + 2
  • Remainder: 77

So, the answer is:

  • Quotient: x2+3x+2x^2 + 3x + 2
  • Remainder: 77
