WebThe discriminant is a quantity such that its sign decides the number of real roots. When it is zero, we have two roots, of which a double one. This double root corresponds to an extremum which is on the horizontal axis (blue curve). By canceling the derivative we solve for , Then plugging in the cubic function, This quantity cancels when WebThe discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation. A positive discriminant indicates that the quadratic has two distinct real number solutions. A discriminant of zero indicates …
