The image contains a mathematical problem involving several equations, and the task is to solve each equation. Let's break down the problem:

**Instructions:**
"Find the quotient, remainder, zero, and root using long division."

**Equations:**
1. \( x^3 - 8x^2 - x + 12 \div x - 2 \)
2. \( x^2 + 1 \div x - 1 \)
3. \( x^4 - 3x^3 + x \div x^2 + 1 \)
4. \( x^3 + 1 \div x - 1 \)

### Solving Each Equation:
#### 1. \( x^3 - 8x^2 - x + 12 \div x - 2 \)
We perform polynomial long division of \( x^3 - 8x^2 - x + 12 \) by \( x - 2 \).

1. **First Step**: Divide the leading term \( x^3 \) by \( x \), which gives \( x^2 \).
2. **Multiply**: \( x^2 \cdot (x - 2) = x^3 - 2x^2 \).
3. **Subtract**: \( (x^3 - 8x^2) - (x^3 - 2x^2) = -6x^2 - x + 12 \).
4. **Repeat**: Continue this process with the next term.

#### 2. \( x^2 + 1 \div x - 1 \)
Similar steps are taken for dividing \( x^2 + 1 \) by \( x - 1 \).

1. **First Step**: Divide \( x^2 \) by \( x \), which gives \( x \).
2. **Multiply**: \( x \cdot (x - 1) = x^2 - x \).
3. **Subtract**: \( (x^2 + 1) - (x^2 - x) = x + 1 \).

#### 3. \( x^4 - 3x^3 + x \div x^2 + 1 \)
For this division, divide \( x^4 - 3x^3 + x \) by \( x^2 + 1 \).

1. **First Step**: Divide \( x^4 \) by \( x^2 \), which gives \( x^2 \).
2. **Multiply**: \( x^2 \cdot (x^2 + 1) = x^4 + x^2 \).
3. **Subtract**: \( (x^4 - 3x^3 + x) - (x^4 + x^2) = -3x^3 - x^2 + x \).

#### 4. \( x^3 + 1 \div x - 1 \)
Finally, divide \( x^3 + 1 \) by \( x - 1 \).

1. **First Step**: Divide \( x^3 \) by \( x \), which gives \( x^2 \).
2. **Multiply**: \( x^2 \cdot (x - 1) = x^3 - x^2 \).
3. **Subtract**: \( (x^3 + 1) - (x^3 - x^2) = x^2 + 1 \).
