If a = 3 and b = -6 in the quadratic ax^2 + bx + c = 0, the sum of the roots equals what?

For a quadratic equation in the form ax^2 + bx + c = 0, the sum of the roots equals negative b divided by a. With a = 3 and b = -6, the sum is -(-6)/3 = 6/3 = 2. The constant term c doesn’t affect the sum, only the product and the individual roots. So the sum of the roots is 2.
