The correct Answer is:
To solve the given equations step by step, we will first tackle each equation separately and then compare the results. ### Step 1: Solve Equation I The first equation is: \[ x^2 - 29x + 208 = 0 \] To factor this quadratic equation, we need to find two numbers that multiply to \( 208 \) and add up to \( -29 \). 1. **Finding the factors**: - The factors of \( 208 \) that add up to \( 29 \) are \( 16 \) and \( 13 \) (since \( 16 + 13 = 29 \)). 2. **Factoring the equation**: \[ x^2 - 29x + 208 = (x - 16)(x - 13) = 0 \] 3. **Finding the values of \( x \)**: - Set each factor to zero: \[ x - 16 = 0 \quad \Rightarrow \quad x = 16 \] \[ x - 13 = 0 \quad \Rightarrow \quad x = 13 \] So, the solutions for the first equation are: \[ x = 16 \quad \text{and} \quad x = 13 \] ### Step 2: Solve Equation II The second equation is: \[ y^2 - 21y + 108 = 0 \] Similarly, we need to find two numbers that multiply to \( 108 \) and add up to \( -21 \). 1. **Finding the factors**: - The factors of \( 108 \) that add up to \( 21 \) are \( 12 \) and \( 9 \) (since \( 12 + 9 = 21 \)). 2. **Factoring the equation**: \[ y^2 - 21y + 108 = (y - 12)(y - 9) = 0 \] 3. **Finding the values of \( y \)**: - Set each factor to zero: \[ y - 12 = 0 \quad \Rightarrow \quad y = 12 \] \[ y - 9 = 0 \quad \Rightarrow \quad y = 9 \] So, the solutions for the second equation are: \[ y = 12 \quad \text{and} \quad y = 9 \] ### Step 3: Compare the Values of \( x \) and \( y \) Now we have the values: - For \( x \): \( 16 \) and \( 13 \) - For \( y \): \( 12 \) and \( 9 \) We will compare each value of \( x \) with each value of \( y \): 1. Compare \( x = 16 \) with \( y = 12 \): - \( 16 > 12 \) 2. Compare \( x = 16 \) with \( y = 9 \): - \( 16 > 9 \) 3. Compare \( x = 13 \) with \( y = 12 \): - \( 13 > 12 \) 4. Compare \( x = 13 \) with \( y = 9 \): - \( 13 > 9 \) ### Conclusion In all comparisons, \( x \) is greater than \( y \). Therefore, the final relation is: \[ x > y \] ### Final Answer The correct option is: **Option A: \( x > y \)**
