Find the remainder when `x^3-a x^2+6x-a` is divided by `x-a`.

Explanation

To find the remainder when the polynomial \( P(x) = x^3 - ax^2 + 6x - a \) is divided by \( x - a \), we can use the Remainder Theorem, which states that the remainder of a polynomial \( P(x) \) when divided by \( x - c \) is \( P(c) \).

### Step-by-Step Solution:

1. **Identify the Polynomial and the Divisor**:
- The polynomial \( P(x) = x^3 - ax^2 + 6x - a \).
- The divisor is \( x - a \).
