This image illustrates the process of polynomial long division. The given expression is divided by \(x - 1\). The long division involves the following steps:

1. **Division Set-Up**:
   - Dividend: \(x^3 + 3x^2 - 2x + 6\)
   - Divisor: \(x - 1\)

2. **First Step**:
   - Divide the first term of the dividend (\(x^3\)) by the first term of the divisor (\(x\)) to get \(x^2\).
   - Multiply \(x^2\) by the divisor \(x - 1\), which gives \(x^3 - x^2\).
   - Subtract \(x^3 - x^2\) from the dividend to get a new dividend of \(4x^2 - 2x\).

3. **Second Step**:
   - Divide the first term of the new dividend (\(4x^2\)) by the first term of the divisor (\(x\)) to get \(4x\).
   - Multiply \(4x\) by the divisor \(x - 1\), which gives \(4x^2 - 4x\).
   - Subtract \(4x^2 - 4x\) from the current dividend to get a new dividend of \(2x + 6\).

4. **Third Step**:
   - Divide the first term of the new dividend (\(2x\)) by the first term of the divisor (\(x\)) to get \(2\).
   - Multiply \(2\) by the divisor \(x - 1\), which gives \(2x - 2\).
   - Subtract \(2x - 2\) from the current dividend to get the remainder \(8\).

5. **Result**:
   - The quotient is \(x^2 + 4x + 2\).
   - The remainder is \(8\).
   
The final expression is:
\[ x^2 + 4x + 2 + \frac{8}{x-1} \]

**Mathematics Problem: Polynomial Division**

**Problem Statement:**
Divide \( 9x^2 + 6x \) by \( 3x \). Show or explain how you got your answer.

**Solution Explanation:**

To divide the polynomial \( 9x^2 + 6x \) by \( 3x \), follow these steps:

1. **Divide Each Term:**
   - **First Term:**
     \[
     \frac{9x^2}{3x} = 3x
     \]
   - **Second Term:**
     \[
     \frac{6x}{3x} = 2
     \]

2. **Combine the Results:**
   - The division yields:
     \[
     3x + 2
     \]

Therefore, the result of dividing \( 9x^2 + 6x \) by \( 3x \) is \( 3x + 2 \).

**Conclusion:**

The division simplifies the polynomial to \( 3x + 2 \). The division process involves simplifying each term independently and then combining the simplified terms to get the final result.
