The correct Answer is:
To solve the given equations step by step, we will start with the first equation and then move on to the second one. ### Step 1: Solve the first equation \(8x^2 + 10x + 3 = 0\) We can use the factorization method here. 1. **Rearranging the equation**: We can rewrite the equation as: \[ 8x^2 + 4x + 6x + 3 = 0 \] 2. **Grouping terms**: Now we can group the terms: \[ (8x^2 + 4x) + (6x + 3) = 0 \] 3. **Factoring out common terms**: From the first group, we can factor out \(4x\): \[ 4x(2x + 1) + 3(2x + 1) = 0 \] 4. **Factoring the entire equation**: Now we can factor out \((2x + 1)\): \[ (2x + 1)(4x + 3) = 0 \] 5. **Finding the roots**: Setting each factor to zero gives: \[ 2x + 1 = 0 \quad \Rightarrow \quad x = -\frac{1}{2} \] \[ 4x + 3 = 0 \quad \Rightarrow \quad x = -\frac{3}{4} \] ### Step 2: Solve the second equation \(2y^2 + 5y + 3 = 0\) Similarly, we will factor this equation. 1. **Rearranging the equation**: We can rewrite the equation as: \[ 2y^2 + 3y + 2y + 3 = 0 \] 2. **Grouping terms**: Now we can group the terms: \[ (2y^2 + 3y) + (2y + 3) = 0 \] 3. **Factoring out common terms**: From the first group, we can factor out \(y\): \[ y(2y + 3) + 1(2y + 3) = 0 \] 4. **Factoring the entire equation**: Now we can factor out \((2y + 3)\): \[ (y + 1)(2y + 3) = 0 \] 5. **Finding the roots**: Setting each factor to zero gives: \[ y + 1 = 0 \quad \Rightarrow \quad y = -1 \] \[ 2y + 3 = 0 \quad \Rightarrow \quad y = -\frac{3}{2} \] ### Step 3: Compare the values of \(x\) and \(y\) Now we have the values: - For \(x\): \(-\frac{1}{2}\) and \(-\frac{3}{4}\) - For \(y\): \(-1\) and \(-\frac{3}{2}\) ### Step 4: Determine the relationship between \(x\) and \(y\) 1. **Comparing \(-\frac{1}{2}\) and \(-1\)**: \(-\frac{1}{2} > -1\) 2. **Comparing \(-\frac{1}{2}\) and \(-\frac{3}{2}\)**: \(-\frac{1}{2} > -\frac{3}{2}\) 3. **Comparing \(-\frac{3}{4}\) and \(-1\)**: \(-\frac{3}{4} > -1\) 4. **Comparing \(-\frac{3}{4}\) and \(-\frac{3}{2}\)**: \(-\frac{3}{4} > -\frac{3}{2}\) ### Conclusion In all cases, the values of \(x\) are greater than the values of \(y\). Therefore, we conclude that: \[ x > y \] ### Final Answer The answer is \(x > y\). ---
