The correct Answer is:
To solve the equations given in the question, we will follow these steps: ### Step 1: Solve the first equation for \( p \) The first equation is: \[ 3p^2 + 17p + 10 = 0 \] To factor this quadratic equation, we look for two numbers that multiply to \( 3 \times 10 = 30 \) and add up to \( 17 \). The numbers \( 15 \) and \( 2 \) fit this requirement. We can rewrite the equation as: \[ 3p^2 + 15p + 2p + 10 = 0 \] Now, we group the terms: \[ (3p^2 + 15p) + (2p + 10) = 0 \] Factoring out the common terms gives us: \[ 3p(p + 5) + 2(p + 5) = 0 \] Now, we can factor out \( (p + 5) \): \[ (3p + 2)(p + 5) = 0 \] Setting each factor to zero gives us: 1. \( 3p + 2 = 0 \) which leads to \( p = -\frac{2}{3} \) 2. \( p + 5 = 0 \) which leads to \( p = -5 \) ### Step 2: Solve the second equation for \( q \) The second equation is: \[ 10q^2 + 9q + 2 = 0 \] We look for two numbers that multiply to \( 10 \times 2 = 20 \) and add up to \( 9 \). The numbers \( 5 \) and \( 4 \) fit this requirement. We can rewrite the equation as: \[ 10q^2 + 5q + 4q + 2 = 0 \] Now, we group the terms: \[ (10q^2 + 5q) + (4q + 2) = 0 \] Factoring out the common terms gives us: \[ 5q(2q + 1) + 2(2q + 1) = 0 \] Now, we can factor out \( (2q + 1) \): \[ (5q + 2)(2q + 1) = 0 \] Setting each factor to zero gives us: 1. \( 5q + 2 = 0 \) which leads to \( q = -\frac{2}{5} \) 2. \( 2q + 1 = 0 \) which leads to \( q = -\frac{1}{2} \) ### Step 3: Compare the values of \( p \) and \( q \) Now we have the values: - For \( p \): \( -\frac{2}{3} \) and \( -5 \) - For \( q \): \( -\frac{2}{5} \) and \( -\frac{1}{2} \) ### Step 4: Determine the order of \( p \) and \( q \) We will compare the values of \( p \) and \( q \): - The values of \( p \) are \( -5 \) and \( -\frac{2}{3} \). - The values of \( q \) are \( -\frac{2}{5} \) and \( -\frac{1}{2} \). To compare: - \( -5 < -\frac{2}{3} \) - \( -\frac{2}{5} > -\frac{1}{2} \) Now, comparing \( -\frac{2}{3} \) and \( -\frac{2}{5} \): - Convert to a common denominator (15): - \( -\frac{2}{3} = -\frac{10}{15} \) - \( -\frac{2}{5} = -\frac{6}{15} \) Thus, \( -\frac{10}{15} < -\frac{6}{15} \) implies \( -\frac{2}{3} < -\frac{2}{5} \). ### Conclusion From the comparisons: - The largest value is \( -\frac{2}{5} \) (for \( q \)), followed by \( -\frac{1}{2} \) (for \( q \)), then \( -\frac{2}{3} \) (for \( p \)), and the smallest is \( -5 \) (for \( p \)). - Therefore, we conclude that \( q > p \). ### Final Answer Thus, the relation is: \[ q > p \] ---
