To determine the values of \( p \) for which the equation will have non-real roots, we need to analyze the expression inside the square root:

\[
x = \frac{5 \pm \sqrt{p(6 - p) - 9}}{2}
\]

The term under the square root, \( p(6 - p) - 9 \), is the discriminant for this quadratic equation. For the roots to be non-real, the discriminant must be **negative**, meaning:

\[
p(6 - p) - 9 < 0
\]

### Step-by-Step Solution

1. **Expand the discriminant inequality**:
   \[
   p(6 - p) - 9 < 0
   \]
   \[
   6p - p^2 - 9 < 0
   \]

2. **Rearrange into standard quadratic form**:
   \[
   -p^2 + 6p - 9 < 0
   \]
   Multiplying by \(-1\) to simplify:
   \[
   p^2 - 6p + 9 > 0
   \]

3. **Factor the quadratic**:
   \[
   (p - 3)^2 > 0
   \]

4. **Solve for \( p \)**:
   The inequality \((p - 3)^2 > 0\) implies that \( p - 3 \neq 0 \), which leads to:
   \[
   p \neq 3
   \]

   Since \((p - 3)^2\) represents a squared term, it is only zero when \( p = 3 \). For the expression to be strictly positive, \( p \) must be any value **other than** 3.

5. **Conclusion**:
   Therefore, the equation will have non-real roots for all values of \( p \) **except** \( p = 3 \).

### Tip:
Remember, for quadratic equations, the nature of the roots depends directly on the discriminant \( b^2 - 4ac \):
- Positive: Two distinct real roots.
- Zero: One real root (repeated).
- Negative: Two non-real (complex) roots.
