The correct Answer is:
To solve the equations and find the relationship between \( p \) and \( q \), we will follow these steps: ### Step 1: Solve the first equation \( 3p^2 + 10p + 8 = 0 \) To solve this quadratic equation, we can use the factorization method. We need to find two numbers that multiply to \( 3 \times 8 = 24 \) and add up to \( 10 \). The numbers that satisfy this are \( 6 \) and \( 4 \). Now we can rewrite the equation: \[ 3p^2 + 6p + 4p + 8 = 0 \] Next, we group the terms: \[ (3p^2 + 6p) + (4p + 8) = 0 \] Factoring out the common terms: \[ 3p(p + 2) + 4(p + 2) = 0 \] Now we can factor by grouping: \[ (3p + 4)(p + 2) = 0 \] Setting each factor to zero gives us: 1. \( 3p + 4 = 0 \) → \( p = -\frac{4}{3} \) 2. \( p + 2 = 0 \) → \( p = -2 \) ### Step 2: Solve the second equation \( 2q^2 + 3q + 1 = 0 \) Similarly, we will factor this quadratic equation. We need to find two numbers that multiply to \( 2 \times 1 = 2 \) and add up to \( 3 \). The numbers that satisfy this are \( 2 \) and \( 1 \). Now we can rewrite the equation: \[ 2q^2 + 2q + q + 1 = 0 \] Next, we group the terms: \[ (2q^2 + 2q) + (q + 1) = 0 \] Factoring out the common terms: \[ 2q(q + 1) + 1(q + 1) = 0 \] Now we can factor by grouping: \[ (2q + 1)(q + 1) = 0 \] Setting each factor to zero gives us: 1. \( 2q + 1 = 0 \) → \( q = -\frac{1}{2} \) 2. \( q + 1 = 0 \) → \( q = -1 \) ### Step 3: Determine the relationship between \( p \) and \( q \) Now we have the values: - For \( p \): \( -\frac{4}{3} \) and \( -2 \) - For \( q \): \( -\frac{1}{2} \) and \( -1 \) We can compare the values: 1. \( -\frac{4}{3} \) (approximately -1.33) is less than \( -1 \) 2. \( -2 \) is less than both \( -\frac{1}{2} \) and \( -1 \) Thus, we can conclude that: \[ p < q \] ### Final Answer The relationship between \( p \) and \( q \) is: \[ p < q \]
