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. ### Step 1: Solve the first equation The first equation is: \[ 5x^2 + 11x + 2 = 0 \] We can use the factorization method. We need to break down the middle term (11x) into two terms that multiply to \(5 \cdot 2 = 10\) and add up to \(11\). We can break it down as \(10x + 1x\). Rewriting the equation: \[ 5x^2 + 10x + 1x + 2 = 0 \] Now, we can group the terms: \[ (5x^2 + 10x) + (1x + 2) = 0 \] Factoring out the common terms: \[ 5x(x + 2) + 1(x + 2) = 0 \] Now we can factor by grouping: \[ (5x + 1)(x + 2) = 0 \] ### Step 2: Set each factor to zero Now we set each factor to zero: 1. \(5x + 1 = 0\) 2. \(x + 2 = 0\) Solving these gives: 1. \(5x + 1 = 0 \Rightarrow 5x = -1 \Rightarrow x = -\frac{1}{5}\) 2. \(x + 2 = 0 \Rightarrow x = -2\) So, the solutions for \(x\) are: \[ x = -\frac{1}{5} \quad \text{and} \quad x = -2 \] ### Step 3: Solve the second equation The second equation is: \[ 4y^2 + 13y + 3 = 0 \] Again, we will factor this equation. We need to break down the middle term (13y) into two terms that multiply to \(4 \cdot 3 = 12\) and add up to \(13\). We can break it down as \(12y + 1y\). Rewriting the equation: \[ 4y^2 + 12y + 1y + 3 = 0 \] Now, we can group the terms: \[ (4y^2 + 12y) + (1y + 3) = 0 \] Factoring out the common terms: \[ 4y(y + 3) + 1(y + 3) = 0 \] Now we can factor by grouping: \[ (4y + 1)(y + 3) = 0 \] ### Step 4: Set each factor to zero Now we set each factor to zero: 1. \(4y + 1 = 0\) 2. \(y + 3 = 0\) Solving these gives: 1. \(4y + 1 = 0 \Rightarrow 4y = -1 \Rightarrow y = -\frac{1}{4}\) 2. \(y + 3 = 0 \Rightarrow y = -3\) So, the solutions for \(y\) are: \[ y = -\frac{1}{4} \quad \text{and} \quad y = -3 \] ### Step 5: Compare the values of \(x\) and \(y\) Now we have the values: - For \(x\): \(x = -\frac{1}{5}, -2\) - For \(y\): \(y = -\frac{1}{4}, -3\) Now we compare: 1. \(x = -\frac{1}{5}\) with \(y = -\frac{1}{4}\): \(-\frac{1}{5} < -\frac{1}{4}\) (since \(-0.2 < -0.25\)) 2. \(x = -\frac{1}{5}\) with \(y = -3\): \(-\frac{1}{5} > -3\) (since \(-0.2 > -3\)) 3. \(x = -2\) with \(y = -\frac{1}{4}\): \(-2 < -\frac{1}{4}\) (since \(-2 < -0.25\)) 4. \(x = -2\) with \(y = -3\): \(-2 > -3\) (since \(-2 > -3\)) ### Conclusion From the comparisons: - \(x = -\frac{1}{5}\) is greater than \(y = -3\) but less than \(y = -\frac{1}{4}\). - \(x = -2\) is greater than \(y = -3\) but less than \(y = -\frac{1}{4}\). Thus, we do not have a consistent relationship between \(x\) and \(y\) across all comparisons. ### Final Answer The relation between \(x\) and \(y\) is that there is no consistent relationship. ---
