The correct Answer is:
To find the sum and the product of the roots of the quadratic equation \(2x^2 + 14x + 24 = 0\), we can use the relationships derived from Vieta's formulas. ### Step-by-Step Solution: 1. **Identify coefficients**: The given quadratic equation is in the standard form \(ax^2 + bx + c = 0\). Here: - \(a = 2\) - \(b = 14\) - \(c = 24\) 2. **Calculate the sum of the roots**: The sum of the roots (\(\alpha + \beta\)) of a quadratic equation can be calculated using the formula: \[ \alpha + \beta = -\frac{b}{a} \] Substituting the values of \(b\) and \(a\): \[ \alpha + \beta = -\frac{14}{2} = -7 \] 3. **Calculate the product of the roots**: The product of the roots (\(\alpha \beta\)) can be calculated using the formula: \[ \alpha \beta = \frac{c}{a} \] Substituting the values of \(c\) and \(a\): \[ \alpha \beta = \frac{24}{2} = 12 \] 4. **Final Result**: Therefore, the sum of the roots is \(-7\) and the product of the roots is \(12\). ### Summary: - Sum of the roots (\(\alpha + \beta\)) = \(-7\) - Product of the roots (\(\alpha \beta\)) = \(12\)
