The correct Answer is:
To find the sum of the roots of the quadratic equation \(x^2 - 6x + 2 = 0\), we can follow these steps: ### Step 1: Identify the coefficients In the standard form of a quadratic equation \(ax^2 + bx + c = 0\), we can identify the coefficients: - \(a = 1\) - \(b = -6\) - \(c = 2\) ### Step 2: Use the formula for the sum of the roots The sum of the roots of a quadratic equation can be calculated using the formula: \[ \text{Sum of the roots} = -\frac{b}{a} \] ### Step 3: Substitute the values of \(b\) and \(a\) Now, we substitute the values of \(b\) and \(a\) into the formula: \[ \text{Sum of the roots} = -\frac{-6}{1} \] ### Step 4: Simplify the expression Now, we simplify the expression: \[ \text{Sum of the roots} = \frac{6}{1} = 6 \] ### Conclusion Thus, the sum of the roots of the equation \(x^2 - 6x + 2 = 0\) is \(6\). ---
