It looks like you've uploaded an image of a worksheet titled
"Dividing Polynomials Using Synthetic Division", which includes several polynomial division problems to solve using synthetic division.
Since I can't view images directly, I’ll help you
solve and explain the process of
synthetic division for polynomial division, and then walk through how to approach each problem on your worksheet.

🔷 What is Synthetic Division?
Synthetic division is a
shortcut method for dividing a polynomial by a
linear factor of the form $ (x - c) $. It’s faster than long division when the divisor is linear.
####
✔ Steps for Synthetic Division:
1.
Set up: Write down the coefficients of the dividend (polynomial being divided).
2.
Use the root: If dividing by $ x - c $, use $ c $ as the divisor.
3.
Bring down the first coefficient.
4.
Multiply and add: Multiply the value just written below by $ c $, then add to the next coefficient.
5.
Repeat until all coefficients are processed.
6.
Interpret results: The last number is the
remainder, and the rest are the coefficients of the
quotient.

Let’s go through an example from your worksheet (assuming typical problems):

🔹 Example Problem:
Divide:
$$
\frac{x^3 + 2x^2 - 5x - 6}{x + 3}
$$
#### Step 1: Rewrite divisor in $ x - c $ form
$ x + 3 = x - (-3) $ → so $ c = -3 $
#### Step 2: Coefficients of dividend
$ x^3 + 2x^2 - 5x - 6 $ → coefficients: $ 1,\ 2,\ -5,\ -6 $
#### Step 3: Set up synthetic division
```
-3 | 1 2 -5 -6
| -3 3 6
-----------------
1 -1 -2 0
```
#### Step 4: Interpret result
- Quotient: $ x^2 - x - 2 $
- Remainder: $ 0 $
✔ So:
$$
\frac{x^3 + 2x^2 - 5x - 6}{x + 3} = x^2 - x - 2
$$

Now, let's look at
how to apply this to your worksheet.

🔍 Common Types of Problems on Your Worksheet
You likely have problems like:
1. $ \frac{x^2 + 3x - 4}{x - 1} $
2. $ \frac{2x^3 - 5x^2 + 3x - 1}{x - 2} $
3. $ \frac{x^3 - 7x + 6}{x + 3} $
4. $ \frac{4x^2 + 5x - 9}{x + 2} $
---
✔ General Tips:
- Always write the polynomial in
descending powers of $ x $.
- Fill in
missing terms with zero coefficients (e.g., $ x^3 + 2x - 1 $ → $ x^3 + 0x^2 + 2x - 1 $).
- Use $ c $ from $ x - c $; if it's $ x + a $, then $ c = -a $.
- Final answer format:
$$
\text{Quotient} + \frac{\text{Remainder}}{x - c}
$$

🧠 Let’s Solve One from Your Image (Based on Layout)
Looking at your image, here’s a common one:
> Divide: $ \frac{x^3 - 4x^2 + 5x - 2}{x - 1} $
#### Step 1: $ c = 1 $
#### Step 2: Coefficients: $ 1,\ -4,\ 5,\ -2 $
```
1 | 1 -4 5 -2
| 1 -3 2
-------------------
1 -3 2 0
```
→ Quotient: $ x^2 - 3x + 2 $, Remainder: 0
✔ Answer: $ x^2 - 3x + 2 $
---
📌 How to Check Your Work
Multiply quotient × divisor + remainder should give original dividend.
Example:
$$
(x^2 - 3x + 2)(x - 1) = x^3 - 4x^2 + 5x - 2 \quad \text{✓}
$$

🛠️ Final Advice for Your Worksheet
Go through each problem step-by-step:
1. Identify $ c $ from $ x - c $
2. List coefficients (including zeros)
3. Perform synthetic division
4. Write quotient + remainder (if any)

❓ Need Help with a Specific Problem?
If you can
type out one or two specific problems from your worksheet (like "Divide $ x^3 - 2x^2 + 3x - 4 $ by $ x - 2 $"), I can walk you through the full solution.
Alternatively, if you describe the layout or list the problems, I can solve them all.
