**Objective:**
Learn how to use long division or synthetic division to divide polynomials.
**Problem:**
Divide the polynomial \( x^3 - 2x^2 + x - 5 \) by \( x - 1 \).
---
**Instructions:**
1. **Long Division Method:**
- Write the dividend \( x^3 - 2x^2 + x - 5 \) and the divisor \( x - 1 \).
- Divide the first term of the dividend by the first term of the divisor.
- Multiply the entire divisor by the result and subtract from the current dividend.
- Repeat the process with the new polynomial formed after subtraction until no terms are left.
2. **Synthetic Division Method:**
- Use the zero of the divisor \( x - 1 \), which is 1.
- List the coefficients of the dividend: 1, -2, 1, -5.
- Bring down the leading coefficient to start the process.
- Multiply the divisor root by the number brought down and add it to the next coefficient.
- Continue through all coefficients.
- The last number is the remainder.
These methods will provide the quotient of the polynomial division, with any remainder. Practice using both to understand the process thoroughly.
