The correct Answer is:
To solve the given quadratic equations and determine the relationship between their solutions, we will follow these steps: ### Step 1: Solve the first equation `p^2 + 5p + 6 = 0`. To solve this quadratic equation, we can factor it. We need to find two numbers that multiply to 6 (the constant term) and add up to 5 (the coefficient of the linear term). The factors of 6 that add up to 5 are 2 and 3. Thus, we can write: \[ p^2 + 5p + 6 = (p + 2)(p + 3) = 0 \] Setting each factor to zero gives us: \[ p + 2 = 0 \quad \Rightarrow \quad p = -2 \] \[ p + 3 = 0 \quad \Rightarrow \quad p = -3 \] ### Step 2: Solve the second equation `q^2 + 3q + 2 = 0`. Similarly, we will factor this quadratic equation. We need two numbers that multiply to 2 and add up to 3. The factors of 2 that add up to 3 are 1 and 2. Thus, we can write: \[ q^2 + 3q + 2 = (q + 1)(q + 2) = 0 \] Setting each factor to zero gives us: \[ q + 1 = 0 \quad \Rightarrow \quad q = -1 \] \[ q + 2 = 0 \quad \Rightarrow \quad q = -2 \] ### Step 3: Compare the values of `p` and `q`. From our solutions, we have: - The values of `p` are -2 and -3. - The values of `q` are -1 and -2. Now, we can compare the values: - For \( p = -2 \), \( q = -2 \) (equal). - For \( p = -3 \), \( q = -1 \) (where \( q > p \)). ### Conclusion: Determine the relationship between `p` and `q`. From the comparisons: - The maximum value of `p` (which is -2) is equal to the minimum value of `q` (which is also -2). - The other value of `p` (-3) is less than the maximum value of `q` (-1). Thus, we conclude that \( q \) is greater than or equal to \( p \). ### Final Answer: The relationship between \( p \) and \( q \) is that \( q \geq p \). ---
