The correct Answer is:
To solve the given quadratic equations and find the relation between \( p \) and \( q \), we will follow these steps: ### Step 1: Solve the first quadratic equation \( p^2 - 7p + 10 = 0 \) We will factor the quadratic equation. We need to find two numbers that multiply to \( 10 \) (the constant term) and add up to \( -7 \) (the coefficient of \( p \)). 1. The numbers that satisfy this are \( -5 \) and \( -2 \). 2. We can rewrite the equation as: \[ p^2 - 5p - 2p + 10 = 0 \] 3. Now, we group the terms: \[ (p^2 - 5p) + (-2p + 10) = 0 \] 4. Factor out the common terms: \[ p(p - 5) - 2(p - 5) = 0 \] 5. This can be factored as: \[ (p - 5)(p - 2) = 0 \] 6. Setting each factor to zero gives us: \[ p - 5 = 0 \quad \Rightarrow \quad p = 5 \] \[ p - 2 = 0 \quad \Rightarrow \quad p = 2 \] So, the solutions for \( p \) are \( p = 2 \) and \( p = 5 \). ### Step 2: Solve the second quadratic equation \( q^2 - 10q + 24 = 0 \) Similarly, we will factor this quadratic equation. We need to find two numbers that multiply to \( 24 \) and add up to \( -10 \). 1. The numbers that satisfy this are \( -6 \) and \( -4 \). 2. We can rewrite the equation as: \[ q^2 - 6q - 4q + 24 = 0 \] 3. Now, we group the terms: \[ (q^2 - 6q) + (-4q + 24) = 0 \] 4. Factor out the common terms: \[ q(q - 6) - 4(q - 6) = 0 \] 5. This can be factored as: \[ (q - 6)(q - 4) = 0 \] 6. Setting each factor to zero gives us: \[ q - 6 = 0 \quad \Rightarrow \quad q = 6 \] \[ q - 4 = 0 \quad \Rightarrow \quad q = 4 \] So, the solutions for \( q \) are \( q = 4 \) and \( q = 6 \). ### Step 3: Find the relation between \( p \) and \( q \) Now we have the values: - \( p = 2 \) and \( p = 5 \) - \( q = 4 \) and \( q = 6 \) We will compare the values of \( p \) and \( q \): - For \( q = 4 \): - \( 4 > 2 \) (so \( q \) is greater than the smaller \( p \)) - \( 4 < 5 \) (so \( q \) is less than the larger \( p \)) - For \( q = 6 \): - \( 6 > 2 \) (so \( q \) is greater than the smaller \( p \)) - \( 6 > 5 \) (so \( q \) is greater than the larger \( p \)) ### Conclusion From the above comparisons, we can conclude that: - \( q = 4 \) is between the two values of \( p \). - \( q = 6 \) is greater than both values of \( p \). Thus, we cannot definitively determine a specific relation between \( p \) and \( q \) since \( q \) can be either between or greater than the values of \( p \).
