The correct Answer is:
To solve the problem, we need to analyze the given quadratic equation \( ax^2 + bx + c = 0 \) under the conditions that the roots are imaginary and \( a + c < b \). ### Step-by-step Solution: 1. **Understanding the Condition for Imaginary Roots**: The roots of a quadratic equation are imaginary if the discriminant \( D \) is less than zero. The discriminant \( D \) is given by: \[ D = b^2 - 4ac \] For the roots to be imaginary: \[ b^2 - 4ac < 0 \] 2. **Analyzing the Condition \( a + c < b \)**: We are given that \( a + c < b \). We can rearrange this inequality: \[ b > a + c \] 3. **Combining the Conditions**: We need to check if both conditions can coexist. From the first condition, we have: \[ b^2 < 4ac \] To explore the implications of \( a + c < b \), we can substitute \( b \) with \( a + c + k \) where \( k > 0 \): \[ (a + c + k)^2 < 4ac \] Expanding this gives: \[ a^2 + 2ac + c^2 + 2k(a + c) + k^2 < 4ac \] Rearranging this leads to: \[ a^2 + c^2 + k^2 + 2k(a + c) < 2ac \] 4. **Conclusion**: The inequality \( a^2 + c^2 + k^2 + 2k(a + c) < 2ac \) suggests that for \( k > 0 \), the left side can be less than the right side under certain conditions. Thus, the conditions \( b^2 < 4ac \) and \( a + c < b \) can coexist, confirming that the roots of the equation are indeed imaginary under the given constraints. ### Final Statement: Therefore, if the roots of the equation \( ax^2 + bx + c = 0 \) are imaginary and \( a + c < b \), then the conditions are consistent with the properties of quadratic equations.
