1. **State the problem:** Determine if the quadratic equation $x^2 - 5x + 6 = 0$ has distinct real roots.
2. **Recall the formula:** For a quadratic equation $ax^2 + bx + c = 0$, the discriminant $\Delta$ is given by:
$$\Delta = b^2 - 4ac$$
3. **Important rule:**
- If $\Delta > 0$, the equation has two distinct real roots.
- If $\Delta = 0$, the equation has exactly one real root (a repeated root).
- If $\Delta < 0$, the equation has no real roots (complex roots).
4. **Identify coefficients:**
Here, $a = 1$, $b = -5$, and $c = 6$.
5. **Calculate the discriminant:**
$$\Delta = (-5)^2 - 4 \times 1 \times 6 = 25 - 24 = 1$$
6. **Interpret the result:**
Since $\Delta = 1 > 0$, the quadratic equation has two distinct real roots.
**Final answer:** The equation $x^2 - 5x + 6 = 0$ has distinct real roots.
