The correct Answer is:
To solve the given equations step by step, we will start with the first equation and then move on to the second equation. ### Step 1: Solve the first equation \( 2x^2 - 3x + 1 = 0 \) 1. **Identify the coefficients**: - \( a = 2 \) - \( b = -3 \) - \( c = 1 \) 2. **Use the quadratic formula**: The quadratic formula is given by: \[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] 3. **Calculate the discriminant**: \[ b^2 - 4ac = (-3)^2 - 4 \cdot 2 \cdot 1 = 9 - 8 = 1 \] 4. **Substitute values into the quadratic formula**: \[ x = \frac{-(-3) \pm \sqrt{1}}{2 \cdot 2} = \frac{3 \pm 1}{4} \] 5. **Calculate the two possible values for \( x \)**: - \( x_1 = \frac{3 + 1}{4} = \frac{4}{4} = 1 \) - \( x_2 = \frac{3 - 1}{4} = \frac{2}{4} = \frac{1}{2} \) Thus, the solutions for \( x \) are: \[ x = 1 \quad \text{and} \quad x = \frac{1}{2} \] ### Step 2: Solve the second equation \( 2y^2 - 5y + 3 = 0 \) 1. **Identify the coefficients**: - \( a = 2 \) - \( b = -5 \) - \( c = 3 \) 2. **Use the quadratic formula**: \[ y = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] 3. **Calculate the discriminant**: \[ b^2 - 4ac = (-5)^2 - 4 \cdot 2 \cdot 3 = 25 - 24 = 1 \] 4. **Substitute values into the quadratic formula**: \[ y = \frac{-(-5) \pm \sqrt{1}}{2 \cdot 2} = \frac{5 \pm 1}{4} \] 5. **Calculate the two possible values for \( y \)**: - \( y_1 = \frac{5 + 1}{4} = \frac{6}{4} = \frac{3}{2} \) - \( y_2 = \frac{5 - 1}{4} = \frac{4}{4} = 1 \) Thus, the solutions for \( y \) are: \[ y = \frac{3}{2} \quad \text{and} \quad y = 1 \] ### Step 3: Compare the values of \( x \) and \( y \) - The values of \( x \) are \( 1 \) and \( \frac{1}{2} \). - The values of \( y \) are \( 1 \) and \( \frac{3}{2} \). Now, we compare: 1. \( \frac{1}{2} < 1 \) 2. \( 1 = 1 \) 3. \( 1 < \frac{3}{2} \) ### Conclusion From the comparisons, we can conclude: - \( x \) can be less than or equal to \( y \). - Therefore, the final relation is: \[ x \leq y \]
