Q: What is the sum of the roots of the quadratic equation x^2 - 6x + 8 = 0?
Solution: Step 1: Use the sum of roots formula -b/a. Here, b = -6, a = 1. Step 2: Sum = 6.
Steps: 5
Step 1: Identify the coefficients of the quadratic equation. In the equation x^2 - 6x + 8 = 0, the coefficient 'a' is 1 (from x^2) and 'b' is -6 (from -6x).
Step 2: Use the formula for the sum of the roots of a quadratic equation, which is -b/a.
Step 3: Substitute the values of 'b' and 'a' into the formula: -(-6)/1.
