The correct Answer is:
To solve the given equations step by step, we will start with each quadratic equation separately. ### Step 1: Solve the first equation \(6x^2 - 5x + 1 = 0\) 1. **Identify the coefficients**: - \(a = 6\), \(b = -5\), \(c = 1\) 2. **Calculate the discriminant**: \[ D = b^2 - 4ac = (-5)^2 - 4 \cdot 6 \cdot 1 = 25 - 24 = 1 \] 3. **Use the quadratic formula**: \[ x = \frac{-b \pm \sqrt{D}}{2a} \] Substituting the values: \[ x = \frac{-(-5) \pm \sqrt{1}}{2 \cdot 6} = \frac{5 \pm 1}{12} \] 4. **Calculate the two possible values for \(x\)**: - First value: \[ x_1 = \frac{5 + 1}{12} = \frac{6}{12} = \frac{1}{2} \] - Second value: \[ x_2 = \frac{5 - 1}{12} = \frac{4}{12} = \frac{1}{3} \] Thus, the solutions for the first equation are: \[ x = \frac{1}{2} \quad \text{and} \quad x = \frac{1}{3} \] ### Step 2: Solve the second equation \(4y^2 - 8y + 3 = 0\) 1. **Identify the coefficients**: - \(a = 4\), \(b = -8\), \(c = 3\) 2. **Calculate the discriminant**: \[ D = b^2 - 4ac = (-8)^2 - 4 \cdot 4 \cdot 3 = 64 - 48 = 16 \] 3. **Use the quadratic formula**: \[ y = \frac{-b \pm \sqrt{D}}{2a} \] Substituting the values: \[ y = \frac{-(-8) \pm \sqrt{16}}{2 \cdot 4} = \frac{8 \pm 4}{8} \] 4. **Calculate the two possible values for \(y\)**: - First value: \[ y_1 = \frac{8 + 4}{8} = \frac{12}{8} = \frac{3}{2} \] - Second value: \[ y_2 = \frac{8 - 4}{8} = \frac{4}{8} = \frac{1}{2} \] Thus, the solutions for the second equation are: \[ y = \frac{3}{2} \quad \text{and} \quad y = \frac{1}{2} \] ### Step 3: Compare the values of \(x\) and \(y\) From the solutions: - \(x = \frac{1}{2}, \frac{1}{3}\) - \(y = \frac{3}{2}, \frac{1}{2}\) We can see that: - The maximum value of \(x\) is \(\frac{1}{2}\) and the minimum value of \(y\) is also \(\frac{1}{2}\). - The maximum value of \(y\) is \(\frac{3}{2}\). Thus, the relationship between \(x\) and \(y\) is: \[ x \leq y \] ### Final Answer The correct relationship is \(x \leq y\).
