The correct Answer is:
To solve the given equations, we will follow these steps: ### Step 1: Solve the first equation \(3x^2 + 11x + 10 = 0\) 1. **Rewrite the equation**: We need to factor the quadratic equation. We can split the middle term (11x) into two parts that add up to 11 and multiply to \(3 \times 10 = 30\). - The two numbers that work are 5 and 6. - Rewrite: \(3x^2 + 5x + 6x + 10 = 0\) 2. **Group the terms**: - Group the first two and the last two terms: \((3x^2 + 5x) + (6x + 10) = 0\) 3. **Factor by grouping**: - From the first group, factor out \(x\): \(x(3x + 5)\) - From the second group, factor out 2: \(2(3x + 5)\) - Combine: \((3x + 5)(x + 2) = 0\) 4. **Set each factor to zero**: - \(3x + 5 = 0 \Rightarrow x = -\frac{5}{3}\) - \(x + 2 = 0 \Rightarrow x = -2\) ### Step 2: Solve the second equation \(2y^2 + 11y + 14 = 0\) 1. **Rewrite the equation**: Again, we will factor the quadratic equation. We need two numbers that add up to 11 and multiply to \(2 \times 14 = 28\). - The two numbers that work are 7 and 4. - Rewrite: \(2y^2 + 7y + 4y + 14 = 0\) 2. **Group the terms**: - Group the first two and the last two terms: \((2y^2 + 7y) + (4y + 14) = 0\) 3. **Factor by grouping**: - From the first group, factor out \(y\): \(y(2y + 7)\) - From the second group, factor out 2: \(2(2y + 7)\) - Combine: \((2y + 7)(y + 2) = 0\) 4. **Set each factor to zero**: - \(2y + 7 = 0 \Rightarrow y = -\frac{7}{2}\) - \(y + 2 = 0 \Rightarrow y = -2\) ### Summary of Solutions - For the first equation, the solutions are \(x = -\frac{5}{3}\) and \(x = -2\). - For the second equation, the solutions are \(y = -\frac{7}{2}\) and \(y = -2\). ### Step 3: Compare the values of \(x\) and \(y\) - We have \(x\) values: \(-\frac{5}{3} \approx -1.67\) and \(-2\). - We have \(y\) values: \(-\frac{7}{2} = -3.5\) and \(-2\). ### Conclusion - The values of \(x\) and \(y\) show that: - For \(x = -\frac{5}{3}\), \(y = -\frac{7}{2}\) gives \(x > y\). - For \(x = -2\), \(y = -2\) gives \(x = y\). Thus, we conclude that \(x \geq y\). ### Final Answer The correct answer is \(x \geq y\). ---
