**Question 18: Polynomial Division**

Given: If \( x - 2 \) divides \( p(x) \) evenly, which statement must be true?

- [ ] 2 is the slope of \( p(x) \)
- [ ] -2 is the y-intercept of \( p(x) \)
- [ ] \( p(2) = 0 \)
- [ ] \( p(-2) = 0 \)

**Explanation:**

To determine which statement is correct, consider the fact that if a polynomial \( p(x) \) is divisible by \( x - 2 \), then \( x = 2 \) is a root of \( p(x) \). This implies that when \( x = 2 \), \( p(2) \) must equal zero. Therefore, the correct option is:

- [ ] \( p(2) = 0 \)

This is a crucial concept in polynomial algebra, particularly in understanding how roots and factors of polynomials are related. When \( x - a \) is a factor of a polynomial \( p(x) \), it means that \( p(a) = 0 \). Thus, if \( x - 2 \) is a factor, \( p(2) \) must be zero.

**Note:** The other options regarding slope and y-intercept are not relevant to determining if \( x - 2 \) divides \( p(x) \) evenly. Also, \( p(-2) = 0 \) corresponds to \( x + 2 \) being a factor, not \( x - 2 \).
