The correct Answer is:
To solve the given quadratic equations and find the relationship between the values of \( x \) and \( y \), we will follow these steps: ### Step 1: Solve the first equation \( 3x^2 - 17x + 10 = 0 \) To factor the quadratic equation, we need to find two numbers that multiply to \( 3 \times 10 = 30 \) and add up to \( -17 \). The numbers are \( -15 \) and \( -2 \). Rewriting the equation: \[ 3x^2 - 15x - 2x + 10 = 0 \] Now, we can group the terms: \[ (3x^2 - 15x) + (-2x + 10) = 0 \] Factoring by grouping: \[ 3x(x - 5) - 2(x - 5) = 0 \] Factoring out the common term: \[ (3x - 2)(x - 5) = 0 \] Setting each factor to zero gives us: \[ 3x - 2 = 0 \quad \text{or} \quad x - 5 = 0 \] Solving these: 1. \( 3x - 2 = 0 \) leads to \( x = \frac{2}{3} \) 2. \( x - 5 = 0 \) leads to \( x = 5 \) Thus, the solutions for \( x \) are: \[ x = \frac{2}{3}, \quad x = 5 \] ### Step 2: Solve the second equation \( 2y^2 - 5y + 3 = 0 \) Similarly, we need to find two numbers that multiply to \( 2 \times 3 = 6 \) and add up to \( -5 \). The numbers are \( -3 \) and \( -2 \). Rewriting the equation: \[ 2y^2 - 3y - 2y + 3 = 0 \] Grouping the terms: \[ (2y^2 - 3y) + (-2y + 3) = 0 \] Factoring by grouping: \[ y(2y - 3) - 1(2y - 3) = 0 \] Factoring out the common term: \[ (2y - 3)(y - 1) = 0 \] Setting each factor to zero gives us: \[ 2y - 3 = 0 \quad \text{or} \quad y - 1 = 0 \] Solving these: 1. \( 2y - 3 = 0 \) leads to \( y = \frac{3}{2} \) 2. \( y - 1 = 0 \) leads to \( y = 1 \) Thus, the solutions for \( y \) are: \[ y = \frac{3}{2}, \quad y = 1 \] ### Step 3: Compare the values of \( x \) and \( y \) Now we have the values: - For \( x \): \( \frac{2}{3}, 5 \) - For \( y \): \( \frac{3}{2}, 1 \) 1. Comparing \( x = \frac{2}{3} \) and \( y = 1 \): \[ \frac{2}{3} < 1 \quad \Rightarrow \quad x < y \] 2. Comparing \( x = \frac{2}{3} \) and \( y = \frac{3}{2} \): \[ \frac{2}{3} < \frac{3}{2} \quad \Rightarrow \quad x < y \] 3. Comparing \( x = 5 \) and \( y = 1 \): \[ 5 > 1 \quad \Rightarrow \quad x > y \] 4. Comparing \( x = 5 \) and \( y = \frac{3}{2} \): \[ 5 > \frac{3}{2} \quad \Rightarrow \quad x > y \] ### Conclusion From the comparisons, we find: - For \( x = \frac{2}{3} \), \( x < y \) - For \( x = 5 \), \( x > y \) Thus, we cannot establish a consistent relationship between \( x \) and \( y \). Therefore, the answer is that there is no definitive relation. ---
