The correct Answer is:
To solve the equations given in the question step by step, we will tackle each quadratic equation separately. ### Step 1: Solve for \( p \) in the equation \( p^2 + 12p + 35 = 0 \) 1. **Identify the coefficients**: - \( a = 1 \) - \( b = 12 \) - \( c = 35 \) 2. **Factor the quadratic**: - We need two numbers that multiply to \( 35 \) (the constant term) and add up to \( 12 \) (the coefficient of \( p \)). - The numbers \( 7 \) and \( 5 \) work because \( 7 \times 5 = 35 \) and \( 7 + 5 = 12 \). 3. **Write the factored form**: \[ (p + 7)(p + 5) = 0 \] 4. **Set each factor to zero**: - \( p + 7 = 0 \) → \( p = -7 \) - \( p + 5 = 0 \) → \( p = -5 \) ### Step 2: Solve for \( q \) in the equation \( 2q^2 + 22q + 56 = 0 \) 1. **Divide the entire equation by 2** to simplify: \[ q^2 + 11q + 28 = 0 \] 2. **Identify the coefficients**: - \( a = 1 \) - \( b = 11 \) - \( c = 28 \) 3. **Factor the quadratic**: - We need two numbers that multiply to \( 28 \) and add up to \( 11 \). - The numbers \( 4 \) and \( 7 \) work because \( 4 \times 7 = 28 \) and \( 4 + 7 = 11 \). 4. **Write the factored form**: \[ (q + 4)(q + 7) = 0 \] 5. **Set each factor to zero**: - \( q + 4 = 0 \) → \( q = -4 \) - \( q + 7 = 0 \) → \( q = -7 \) ### Step 3: Compare the values of \( p \) and \( q \) - The values obtained are: - \( p = -7 \) or \( p = -5 \) - \( q = -4 \) or \( q = -7 \) ### Step 4: Determine the relationship between \( p \) and \( q \) 1. **Compare the values**: - For \( p = -7 \) and \( q = -7 \): \( p = q \) - For \( p = -5 \) and \( q = -4 \): \( q > p \) ### Conclusion The relationship between \( p \) and \( q \) is that \( q \) is greater than or equal to \( p \). ---
