the sum and the product of roots of quadratic equation

Sagot :

First, know your quadratic equation. The formula for the sum of roots is -b/a. And the formula for the product of roots is c/a. So IF (this is an example) your quadratic equation is x^2 + 2x - 8 = 0, the sum of the roots is -2 and the product of the roots is -8.
