1. **Problem Statement:** Solve the quadratic equation $x^2 - 5x + 6 = 0$ using the quadratic formula.
2. **Formula Used:** The quadratic formula to solve $ax^2 + bx + c = 0$ is:
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
where $a$, $b$, and $c$ are coefficients of the quadratic equation.
3. **Identify coefficients:** For the equation $x^2 - 5x + 6 = 0$, we have:
- $a = 1$
- $b = -5$
- $c = 6$
4. **Calculate the discriminant:**
$$\Delta = b^2 - 4ac = (-5)^2 - 4 \times 1 \times 6 = 25 - 24 = 1$$
5. **Apply the quadratic formula:**
$$x = \frac{-(-5) \pm \sqrt{1}}{2 \times 1} = \frac{5 \pm 1}{2}$$
6. **Find the two roots:**
- For the plus sign:
$$x_1 = \frac{5 + 1}{2} = \frac{6}{2} = 3$$
- For the minus sign:
$$x_2 = \frac{5 - 1}{2} = \frac{4}{2} = 2$$
7. **Conclusion:** The solutions to the quadratic equation $x^2 - 5x + 6 = 0$ are $x = 3$ and $x = 2$.
These roots satisfy the original equation when substituted back.
