WebSum and Product of Roots. The quadratic formula. x = − b ± b 2 − 4 a c 2 a. give the roots of a quadratic equation which may be real or imaginary. The ± sign in the radical indicates that. x 1 = − b + b 2 − 4 a c 2 a and x 2 = − b − b 2 − 4 a c 2 a. where x 1 and x 2 are the roots of the quadratic equation ax 2 + bx + c = 0. WebThe sum of the roots is (5 + √2) + (5 − √2) = 10. The product of the roots is (5 + √2) (5 − √2) = 25 − 2 = 23. And we want an equation like: ax2 + bx + c = 0. When a=1 we can work out that: Sum of the roots = −b/a = -b. Product … WebThe sum and product of the roots can be rewritten using the two formulas above. Example 1. The example below illustrates how this formula applies to the quadratic equation x 2 + 5 x + 6. As you can see the sum of the roots is indeed − b a and the product of the roots is c a . … luxury rental cars atlanta airport
