The correct Answer is:
To solve the given equations step by step, we will tackle each quadratic equation separately. ### Step 1: Solve the first equation \( I: x^2 - 3x + 2 = 0 \) 1. **Identify the coefficients**: - Here, \( a = 1 \), \( b = -3 \), and \( c = 2 \). 2. **Factor the quadratic equation**: - We need to find two numbers that multiply to \( ac = 1 \times 2 = 2 \) and add up to \( b = -3 \). - The numbers are \( -1 \) and \( -2 \). - Therefore, we can factor the equation as: \[ (x - 1)(x - 2) = 0 \] 3. **Set each factor to zero**: - \( x - 1 = 0 \) → \( x = 1 \) - \( x - 2 = 0 \) → \( x = 2 \) 4. **Solutions for x**: - The solutions for the first equation are \( x = 1 \) and \( x = 2 \). ### Step 2: Solve the second equation \( II: 2y^2 - 7y + 6 = 0 \) 1. **Identify the coefficients**: - Here, \( a = 2 \), \( b = -7 \), and \( c = 6 \). 2. **Factor the quadratic equation**: - We need to find two numbers that multiply to \( ac = 2 \times 6 = 12 \) and add up to \( b = -7 \). - The numbers are \( -3 \) and \( -4 \). - Therefore, we can rewrite the equation as: \[ 2y^2 - 3y - 4y + 6 = 0 \] - Now, factor by grouping: \[ y(2y - 3) - 2(2y - 3) = 0 \] \[ (2y - 3)(y - 2) = 0 \] 3. **Set each factor to zero**: - \( 2y - 3 = 0 \) → \( y = \frac{3}{2} = 1.5 \) - \( y - 2 = 0 \) → \( y = 2 \) 4. **Solutions for y**: - The solutions for the second equation are \( y = 1.5 \) and \( y = 2 \). ### Step 3: Compare the solutions - From the first equation, we have \( x = 1 \) and \( x = 2 \). - From the second equation, we have \( y = 1.5 \) and \( y = 2 \). ### Step 4: Determine the relationship between x and y - The possible pairs are: - If \( x = 1 \), then \( y = 1.5 \) (1 < 1.5) - If \( x = 2 \), then \( y = 2 \) (2 = 2) Thus, we can conclude that \( y \) is greater than or equal to \( x \). ### Final Answer: The correct relation is \( x \leq y \). ---
