The correct Answer is:
To solve the given equations and determine the relationship between the values of \(x\) and \(y\), we will follow these steps: ### Step 1: Solve the first equation \(6x^2 + 5x + 1 = 0\) We will factor the quadratic equation. We need to find two numbers that multiply to \(6 \times 1 = 6\) and add up to \(5\). 1. The numbers \(3\) and \(2\) satisfy this condition. 2. Rewrite \(5x\) as \(3x + 2x\): \[ 6x^2 + 3x + 2x + 1 = 0 \] 3. Group the terms: \[ (6x^2 + 3x) + (2x + 1) = 0 \] 4. Factor by grouping: \[ 3x(2x + 1) + 1(2x + 1) = 0 \] 5. Factor out the common term \((2x + 1)\): \[ (2x + 1)(3x + 1) = 0 \] ### Step 2: Find the values of \(x\) Set each factor equal to zero: 1. \(2x + 1 = 0\) gives: \[ x = -\frac{1}{2} \] 2. \(3x + 1 = 0\) gives: \[ x = -\frac{1}{3} \] ### Step 3: Solve the second equation \(2y^2 + 5y + 3 = 0\) Similarly, we will factor this quadratic equation. We need two numbers that multiply to \(2 \times 3 = 6\) and add up to \(5\). 1. The numbers \(2\) and \(3\) satisfy this condition. 2. Rewrite \(5y\) as \(2y + 3y\): \[ 2y^2 + 2y + 3y + 3 = 0 \] 3. Group the terms: \[ (2y^2 + 2y) + (3y + 3) = 0 \] 4. Factor by grouping: \[ 2y(y + 1) + 3(y + 1) = 0 \] 5. Factor out the common term \((y + 1)\): \[ (y + 1)(2y + 3) = 0 \] ### Step 4: Find the values of \(y\) Set each factor equal to zero: 1. \(y + 1 = 0\) gives: \[ y = -1 \] 2. \(2y + 3 = 0\) gives: \[ y = -\frac{3}{2} \] ### Step 5: Compare the values of \(x\) and \(y\) Now we have: - Values of \(x\): \(-\frac{1}{2}\) and \(-\frac{1}{3}\) - Values of \(y\): \(-1\) and \(-\frac{3}{2}\) We will compare these values: 1. Compare \(x = -\frac{1}{2}\) with \(y = -1\): \[ -\frac{1}{2} > -1 \quad \text{(True)} \] 2. Compare \(x = -\frac{1}{2}\) with \(y = -\frac{3}{2}\): \[ -\frac{1}{2} > -\frac{3}{2} \quad \text{(True)} \] 3. Compare \(x = -\frac{1}{3}\) with \(y = -1\): \[ -\frac{1}{3} > -1 \quad \text{(True)} \] 4. Compare \(x = -\frac{1}{3}\) with \(y = -\frac{3}{2}\): \[ -\frac{1}{3} > -\frac{3}{2} \quad \text{(True)} \] ### Conclusion In all comparisons, \(x\) is greater than \(y\). Therefore, the correct relationship is: \[ x > y \]
