1. **Problem Statement:** Perform synthetic division of a polynomial by a linear divisor of the form $x - c$.
2. **Formula and Rules:** Synthetic division is a shortcut method for dividing a polynomial $P(x)$ by $x - c$. The key steps involve using the root $c$ and the coefficients of $P(x)$.
3. **Step-by-step process:**
- Write down the coefficients of the polynomial.
- Bring down the leading coefficient.
- Multiply it by $c$ and write the result under the next coefficient.
- Add the column and repeat until all coefficients are processed.
4. **Example:** Divide $2x^3 - 6x^2 + 2x - 1$ by $x - 3$.
- Coefficients: 2, -6, 2, -1
- Root $c = 3$
5. **Perform synthetic division:**
\begin{align*}
&\text{Bring down } 2 \
&2 \times 3 = 6 \quad \Rightarrow -6 + 6 = 0 \
&0 \times 3 = 0 \quad \Rightarrow 2 + 0 = 2 \
&2 \times 3 = 6 \quad \Rightarrow -1 + 6 = 5
\end{align*}
6. **Result:** The quotient polynomial is $2x^2 + 0x + 2 = 2x^2 + 2$ and the remainder is $5$.
7. **Final answer:**
$$\frac{2x^3 - 6x^2 + 2x - 1}{x - 3} = 2x^2 + 2 + \frac{5}{x - 3}$$
