The correct Answer is:
To solve the given equations and compare the values of \( p \) and \( q \), we will follow these steps: ### Step 1: Solve the first equation for \( p \) The first equation is: \[ p^2 - 18p + 77 = 0 \] To factor this quadratic equation, we look for two numbers that multiply to \( 77 \) and add up to \( -18 \). The numbers are \( -11 \) and \( -7 \). Thus, we can rewrite the equation as: \[ (p - 11)(p - 7) = 0 \] Setting each factor to zero gives us: 1. \( p - 11 = 0 \) → \( p = 11 \) 2. \( p - 7 = 0 \) → \( p = 7 \) So, the values of \( p \) are \( 11 \) and \( 7 \). ### Step 2: Solve the second equation for \( q \) The second equation is: \[ 3q^2 - 25q + 28 = 0 \] To factor this quadratic equation, we need to find two numbers that multiply to \( 3 \times 28 = 84 \) and add up to \( -25 \). The numbers are \( -21 \) and \( -4 \). We can rewrite the equation as: \[ 3q^2 - 21q - 4q + 28 = 0 \] Grouping the terms gives us: \[ 3q(q - 7) - 4(q - 7) = 0 \] Factoring out \( (q - 7) \) gives: \[ (3q - 4)(q - 7) = 0 \] Setting each factor to zero gives us: 1. \( 3q - 4 = 0 \) → \( q = \frac{4}{3} \) 2. \( q - 7 = 0 \) → \( q = 7 \) So, the values of \( q \) are \( \frac{4}{3} \) and \( 7 \). ### Step 3: Compare the values of \( p \) and \( q \) Now we have: - Values of \( p \): \( 11, 7 \) - Values of \( q \): \( \frac{4}{3}, 7 \) We will compare these values: - When \( p = 11 \), \( 11 > 7 \) and \( 11 > \frac{4}{3} \). - When \( p = 7 \), \( 7 = 7 \) and \( 7 > \frac{4}{3} \). ### Conclusion From the comparisons: - The maximum value of \( p \) (which is \( 11 \)) is greater than the maximum value of \( q \) (which is \( 7 \)). - The value \( 7 \) for \( p \) is equal to the value \( 7 \) for \( q \). Thus, we conclude that: **Quantity I (values of \( p \)) is greater than or equal to Quantity II (values of \( q \)).** ### Final Answer **Quantity I is greater than or equal to Quantity II.** ---
