What Is a Discriminant? In Math Remember the quadratic formula? The discriminant can be a positive number, a negative number, or a zero. It determines the number of possible solutions to the given quadratic equation - A positive discriminant shows that a quadratic equation has two distinct real number solutions. This skill use to just apply to trigonometry, but we see it pop up with algebra more often now.
Does the discriminant give the exact roots of a quadratic equation the points where the parabola crosses the x axis. The discriminant is an important element to consider when solving quadratic equations and this quizworksheet will help you test your understanding of it as well as its effect on quadratic equations.
