Correct Answer: 7
Steps
Concepts
Step 1: Identify the coefficients in the quadratic equation x^2 - 7x + 10 = 0. Here, a = 1, b = -7, and c = 10.
Step 2: Use the formula for the sum of the roots of a quadratic equation, which is -b/a.
Step 3: Substitute the value of b (-7) and a (1) into the formula: -(-7)/1.
Step 4: Simplify the expression: 7/1 = 7.
Step 5: Conclude that the sum of the roots is 7.
