The correct Answer is:
To solve the given equations step by step, we will tackle each quadratic equation separately. ### Step 1: Solve Equation I: \(3x^2 + 4x + 1 = 0\) 1. **Identify the coefficients**: - Here, \(a = 3\), \(b = 4\), and \(c = 1\). 2. **Use the quadratic formula**: The quadratic formula is given by: \[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] 3. **Calculate the discriminant**: \[ b^2 - 4ac = 4^2 - 4 \cdot 3 \cdot 1 = 16 - 12 = 4 \] Since the discriminant is positive, we will have two real solutions. 4. **Substitute values into the quadratic formula**: \[ x = \frac{-4 \pm \sqrt{4}}{2 \cdot 3} = \frac{-4 \pm 2}{6} \] 5. **Calculate the two possible values for \(x\)**: - First solution: \[ x_1 = \frac{-4 + 2}{6} = \frac{-2}{6} = -\frac{1}{3} \] - Second solution: \[ x_2 = \frac{-4 - 2}{6} = \frac{-6}{6} = -1 \] Thus, the solutions for Equation I are: \[ x = -1 \quad \text{and} \quad x = -\frac{1}{3} \] ### Step 2: Solve Equation II: \(y^2 + 5y + 6 = 0\) 1. **Identify the coefficients**: - Here, \(a = 1\), \(b = 5\), and \(c = 6\). 2. **Use the quadratic formula**: \[ y = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] 3. **Calculate the discriminant**: \[ b^2 - 4ac = 5^2 - 4 \cdot 1 \cdot 6 = 25 - 24 = 1 \] Since the discriminant is positive, we will have two real solutions. 4. **Substitute values into the quadratic formula**: \[ y = \frac{-5 \pm \sqrt{1}}{2 \cdot 1} = \frac{-5 \pm 1}{2} \] 5. **Calculate the two possible values for \(y\)**: - First solution: \[ y_1 = \frac{-5 + 1}{2} = \frac{-4}{2} = -2 \] - Second solution: \[ y_2 = \frac{-5 - 1}{2} = \frac{-6}{2} = -3 \] Thus, the solutions for Equation II are: \[ y = -2 \quad \text{and} \quad y = -3 \] ### Conclusion The solutions to the equations are: - From Equation I: \(x = -1\) and \(x = -\frac{1}{3}\) - From Equation II: \(y = -2\) and \(y = -3\) ### Step 3: Compare the values of \(x\) and \(y\) - Compare \(x\) values with \(y\) values: - For \(x = -1\) and \(y = -2\): \(-1 > -2\) - For \(x = -\frac{1}{3}\) and \(y = -3\): \(-\frac{1}{3} > -3\) Both comparisons show that \(x\) is greater than \(y\). ### Final Answer The relation is \(x > y\). ---
