The correct Answer is:
To solve the given quadratic equations step by step, we will follow the standard method of factoring or using the quadratic formula. ### Step 1: Solve the first equation \(12x^2 + 11x + 2 = 0\) 1. **Identify coefficients**: - \(a = 12\), \(b = 11\), \(c = 2\) 2. **Use the quadratic formula**: The quadratic formula is given by: \[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] 3. **Calculate the discriminant**: \[ D = b^2 - 4ac = 11^2 - 4 \cdot 12 \cdot 2 = 121 - 96 = 25 \] 4. **Calculate the roots**: \[ x = \frac{-11 \pm \sqrt{25}}{2 \cdot 12} = \frac{-11 \pm 5}{24} \] - For \(x_1\): \[ x_1 = \frac{-11 + 5}{24} = \frac{-6}{24} = -\frac{1}{4} \] - For \(x_2\): \[ x_2 = \frac{-11 - 5}{24} = \frac{-16}{24} = -\frac{2}{3} \] ### Step 2: Solve the second equation \(12y^2 + 7y + 1 = 0\) 1. **Identify coefficients**: - \(a = 12\), \(b = 7\), \(c = 1\) 2. **Use the quadratic formula**: \[ y = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] 3. **Calculate the discriminant**: \[ D = b^2 - 4ac = 7^2 - 4 \cdot 12 \cdot 1 = 49 - 48 = 1 \] 4. **Calculate the roots**: \[ y = \frac{-7 \pm \sqrt{1}}{2 \cdot 12} = \frac{-7 \pm 1}{24} \] - For \(y_1\): \[ y_1 = \frac{-7 + 1}{24} = \frac{-6}{24} = -\frac{1}{4} \] - For \(y_2\): \[ y_2 = \frac{-7 - 1}{24} = \frac{-8}{24} = -\frac{1}{3} \] ### Step 3: Compare the values of \(x\) and \(y\) - The values obtained are: - From the first equation: \(x_1 = -\frac{1}{4}\), \(x_2 = -\frac{2}{3}\) - From the second equation: \(y_1 = -\frac{1}{4}\), \(y_2 = -\frac{1}{3}\) ### Step 4: Determine the relationship - Comparing the values: - \(y_1 = -\frac{1}{4}\) is equal to \(x_1 = -\frac{1}{4}\) - \(y_2 = -\frac{1}{3}\) is greater than \(x_2 = -\frac{2}{3}\) Thus, we can conclude that \(y\) is greater than or equal to \(x\). ### Final Answer: The correct option is \(x \leq y\).
