The result of the division is x+16. So, (x^2 +8x+1)÷(x−4)=x+16.

To perform synthetic division, we'll be dividing the polynomial

x^2 +8x+1 by the binomial x−4. The synthetic division process involves setting up a table and performing a series of calculations.

The dividend is x^2 +8x+1, and the divisor is x−4.

To use synthetic division, we'll use the root x=4 because the divisor is x−4.

Here's the setup:

4 | 1 8 1

Now, bring down the first coefficient:

4 | 1 8 1

-----------------

|

Multiply the divisor (4) by the first term (1) and write the result below the line:

4 | 1 8 1

-----------------

| 4

Add the corresponding terms:

4 | 1 8 1

-----------------

| 4

-----------

1 12

Repeat the process:

4 | 1 8 1

-----------------

| 4

-----------

1 12

---------

1 16

Now, the numbers in the bottom row represent the coefficients of the quotient. So, the quotient is 1x+16, and the remainder is 0. Therefore, the result of the division is x+16.

So, (x^2 +8x+1)÷(x−4)=x+16.
