Quadratic Solution 66E176
1. **Problem Statement:** Solve the equation $x^2 - 5x + 6 = 0$.
2. **Formula and Rules:** This is a quadratic equation of the form $ax^2 + bx + c = 0$.
The solutions can be found using the quadratic formula:
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
where $a=1$, $b=-5$, and $c=6$.
3. **Calculate the discriminant:**
$$\Delta = b^2 - 4ac = (-5)^2 - 4 \times 1 \times 6 = 25 - 24 = 1$$
4. **Find the roots:**
$$x = \frac{-(-5) \pm \sqrt{1}}{2 \times 1} = \frac{5 \pm 1}{2}$$
5. **Evaluate each root:**
- For $+$ sign: $x = \frac{5 + 1}{2} = \frac{6}{2} = 3$
- For $-$ sign: $x = \frac{5 - 1}{2} = \frac{4}{2} = 2$
6. **Final answer:** The solutions to the equation are $x=3$ and $x=2$.
These values satisfy the original quadratic equation.
