make 5 example of SOLVING QUADRATIC EQUATION BY QUOTIENT RULE

The quotient rule is typically used in calculus for differentiating functions, not for solving quadratic equations. However, you might be referring to solving quadratic equations by the method of factoring or by completing the square. I'll provide examples based on that assumption. If you meant something else, please clarify.

### Example 1: Solving by Factoring

**Equation:**  
\[ x^2 - 5x + 6 = 0 \]

**Solution:**
1. Factor the quadratic: \((x - 2)(x - 3) = 0\)
2. Set each factor equal to zero:
   - \(x - 2 = 0 \Rightarrow x = 2\)
   - \(x - 3 = 0 \Rightarrow x = 3\)

**Final Answer:**  
\(x = 2\) or \(x = 3\)

### Example 2: Solving by Completing the Square

**Equation:**  
\[ x^2 + 6x + 5 = 0 \]

**Solution:**
1. Move the constant term to the right side:  
   \[ x^2 + 6x = -5 \]
2. Add \(\left(\frac{6}{2}\right)^2 = 9\) to both sides:  
   \[ x^2 + 6x + 9 = 4 \]
3. Factor the left side:  
   \[ (x + 3)^2 = 4 \]
4. Take the square root of both sides:  
   \[ x + 3 = \pm 2 \]
5. Solve for \(x\):
   - \(x + 3 = 2 \Rightarrow x = -1\)
   - \(x + 3 = -2 \Rightarrow x = -5\)

**Final Answer:**  
\(x = -1\) or \(x = -5\)

### Example 3: Solving by Factoring

**Equation:**  
\[ 2x^2 - 8x = 0 \]

**Solution:**
1. Factor out the common term:  
   \[ 2x(x - 4) = 0 \]
2. Set each factor equal to zero:
   - \(2x = 0 \Rightarrow x = 0\)
   - \(x - 4 = 0 \Rightarrow x = 4\)

**Final Answer:**  
\(x = 0\) or \(x = 4\)

### Example 4: Solving by Completing the Square

**Equation:**  
\[ x^2 - 4x + 1 = 0 \]

**Solution:**
1. Move the constant term to the right side:  
   \[ x^2 - 4x = -1 \]
2. Add \(\left(\frac{-4}{2}\right)^2 = 4\) to both sides:  
   \[ x^2 - 4x + 4 = 3 \]
3. Factor the left side:  
   \[ (x - 2)^2 = 3 \]
4. Take the square root of both sides:  
   \[ x - 2 = \pm\sqrt{3} \]
5. Solve for \(x\):
   - \(x - 2 = \sqrt{3} \Rightarrow x = 2 + \sqrt{3}\)
   - \(x - 2 = -\sqrt{3} \Rightarrow x = 2 - \sqrt{3}\)

**Final Answer:**  
\(x = 2 + \sqrt{3}\) or \(x = 2 - \sqrt{3}\)

### Example 5: Solving by Factoring

**Equation:**  
\[ 3x^2 - 12x + 9 = 0 \]

**Solution:**
1. Factor the quadratic:  
   \[ 3(x^2 - 4x + 3) = 0 \]
2. Factor the expression inside the parentheses:  
   \[ 3(x - 3)(x - 1) = 0 \]
3. Set each factor equal to zero:
   - \(x - 3 = 0 \Rightarrow x = 3\)
   - \(x - 1 = 0 \Rightarrow x = 1\)

**Final Answer:**  
\(x = 3\) or \(x = 1\)
