The correct Answer is:
To solve the given equations step by step, we will first tackle each equation separately. ### Step 1: Solve the first equation \(8x^2 - 10x + 3 = 0\) 1. **Identify the coefficients**: - \(a = 8\), \(b = -10\), \(c = 3\) 2. **Use the quadratic formula**: The quadratic formula is given by: \[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] 3. **Calculate the discriminant**: \[ b^2 - 4ac = (-10)^2 - 4 \cdot 8 \cdot 3 = 100 - 96 = 4 \] 4. **Substitute values into the quadratic formula**: \[ x = \frac{-(-10) \pm \sqrt{4}}{2 \cdot 8} = \frac{10 \pm 2}{16} \] 5. **Calculate the two possible values for \(x\)**: - First value: \[ x_1 = \frac{10 + 2}{16} = \frac{12}{16} = \frac{3}{4} \] - Second value: \[ x_2 = \frac{10 - 2}{16} = \frac{8}{16} = \frac{1}{2} \] ### Step 2: Solve the second equation \(5y^2 + 14y - 3 = 0\) 1. **Identify the coefficients**: - \(a = 5\), \(b = 14\), \(c = -3\) 2. **Use the quadratic formula**: \[ y = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] 3. **Calculate the discriminant**: \[ b^2 - 4ac = (14)^2 - 4 \cdot 5 \cdot (-3) = 196 + 60 = 256 \] 4. **Substitute values into the quadratic formula**: \[ y = \frac{-14 \pm \sqrt{256}}{2 \cdot 5} = \frac{-14 \pm 16}{10} \] 5. **Calculate the two possible values for \(y\)**: - First value: \[ y_1 = \frac{-14 + 16}{10} = \frac{2}{10} = \frac{1}{5} \] - Second value: \[ y_2 = \frac{-14 - 16}{10} = \frac{-30}{10} = -3 \] ### Summary of Solutions - The values of \(x\) are \(\frac{3}{4}\) and \(\frac{1}{2}\). - The values of \(y\) are \(\frac{1}{5}\) and \(-3\). ### Step 3: Compare the values of \(x\) and \(y\) 1. **Compare \(x_1 = \frac{1}{2}\) with both \(y\) values**: - \(\frac{1}{2} > -3\) (True) - \(\frac{1}{2} > \frac{1}{5}\) (True) 2. **Compare \(x_2 = \frac{3}{4}\) with both \(y\) values**: - \(\frac{3}{4} > -3\) (True) - \(\frac{3}{4} > \frac{1}{5}\) (True) ### Conclusion From the comparisons, we can conclude that for both values of \(x\), \(x\) is greater than \(y\). Therefore, the final relation is: \[ x > y \]
