The correct Answer is:
To find the sum of the zeroes of the polynomial \(2x^2 - 8x + 6\), we can use the formula for the sum of the zeroes of a quadratic polynomial \(ax^2 + bx + c\), which is given by: \[ \text{Sum of zeroes} = -\frac{b}{a} \] ### Step-by-step Solution: 1. **Identify the coefficients**: In the polynomial \(2x^2 - 8x + 6\), we identify the coefficients: - \(a = 2\) (coefficient of \(x^2\)) - \(b = -8\) (coefficient of \(x\)) - \(c = 6\) (constant term) 2. **Apply the formula**: We will substitute the values of \(a\) and \(b\) into the formula: \[ \text{Sum of zeroes} = -\frac{b}{a} = -\frac{-8}{2} \] 3. **Calculate the sum**: Simplifying the expression: \[ \text{Sum of zeroes} = \frac{8}{2} = 4 \] 4. **Final answer**: Therefore, the sum of the zeroes of the polynomial \(2x^2 - 8x + 6\) is \(4\).
