Title: Polynomial Division Techniques

---

**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.
