The correct Answer is:
To solve the problem step by step, we will analyze the given equations and statements. ### Step 1: Identify the roots of the first equation The first equation is given as: \[ x^2 + 2px + q = 0 \] Let the roots be \( \alpha \) and \( \beta \). Using Vieta's formulas, we know: - The sum of the roots \( \alpha + \beta = -2p \) - The product of the roots \( \alpha \beta = q \) ### Step 2: Identify the roots of the second equation The second equation is given as: \[ ax^2 + 2bx + c = 0 \] The roots of this equation are \( \alpha \) and \( \frac{1}{\beta} \). Again, using Vieta's formulas, we have: - The sum of the roots \( \alpha + \frac{1}{\beta} = -\frac{2b}{a} \) - The product of the roots \( \alpha \cdot \frac{1}{\beta} = \frac{c}{a} \) ### Step 3: Express \( \beta \) in terms of \( \alpha \) From the first equation: \[ \beta = -2p - \alpha \] Substituting this into the product of the roots gives: \[ \alpha \left(-\frac{1}{2p + \alpha}\right) = \frac{c}{a} \] ### Step 4: Analyze the statements **Statement I:** \[ (p^2 - q)(b^2 - ac) \geq 0 \] We know: - \( p^2 = \left(\frac{\alpha + \beta}{-2}\right)^2 \) - \( q = \alpha \beta \) Substituting these into the expression, we can analyze whether it holds true. **Statement II:** \[ b \notin pa \quad \text{or} \quad c \notin qa \] This statement suggests that \( b \) and \( c \) cannot be expressed in terms of \( p \) and \( q \) respectively. ### Step 5: Verify Statement I We need to show that: \[ (p^2 - q)(b^2 - ac) \geq 0 \] Using the derived expressions for \( p^2 \) and \( q \), we can substitute and simplify to check if the inequality holds. ### Step 6: Verify Statement II We need to check if \( b \) can be expressed as \( pa \) or if \( c \) can be expressed as \( qa \). Given that \( \beta \) is not equal to -1, 0, or 1, we can conclude that these expressions do not hold true. ### Conclusion After analyzing both statements, we conclude that: - **Statement I** is true. - **Statement II** is also true but does not provide a correct explanation for Statement I.

To solve the problem step by step, we will analyze the given equations and statements. ### Step 1: Identify the roots of the first equation The first equation is given as: \[ x^2 + 2px + q = 0 \] Let the roots be \( \alpha \) and \( \beta \). Using Vieta's formulas, we know: ...
