Complete the synthetic division problem below.

\[ -1 \mid 2 \quad 9 \quad 7 \]

What is the quotient in polynomial form?

Answer :

Quotient in polynomial form is 2x + 7.

To complete the synthetic division problem, we start with the coefficients 2, 9, and 7 of the polynomial and the number -1. Here is the step-by-step process:

  1. Bring down the leading coefficient (2) to the bottom row.
  2. Multiply -1 by the number just written down (2), and write the result above the next coefficient.
  3. Add the numbers in the column (9 + (-2) = 7) and write the result in the bottom row.
  4. Repeat this process until each coefficient has been used.

The final row contains the coefficients of the quotient polynomial.

Performing these steps, we get:

  • Down 2,
  • Multiply -1 by 2 to get -2, then add 9 to get 7 (above the 7).
  • Multiply -1 by 7 to get -7, then add 7 to get 0 (remainder).

The quotient in polynomial form is thus 2x + 7.

Answer:

2x+7

Step-by-step explanation:

See the attachment for the working and an explanation of how you find the numbers in the table.

The quotient is 2x+7.
