Show that (x-3) is a factor of the polynomial `x^(3)+x^(2)-17x+15`.

Explanation

To show that \( (x - 3) \) is a factor of the polynomial \( x^3 + x^2 - 17x + 15 \), we will use the Factor Theorem. According to the Factor Theorem, if \( (x - c) \) is a factor of a polynomial \( P(x) \), then \( P(c) = 0 \).

### Step-by-Step Solution:

1. **Identify the Polynomial**:
The polynomial given is:
\[
P(x) = x^3 + x^2 - 17x + 15
