How Do You Find The Discriminant of a Quadratic Equation With 2 Solutions?
Note:
In a quadratic equation, the discriminant helps tell you the number of real solutions to a quadratic equation. In this tutorial, see how to find the discriminant of a quadratic equation and use it to determine the number of solutions!
Background Tutorials
-
Use the method of completing the square to transform any quadratic equation in x into an equation of the form (x - p)^2= q that has the same solutions. Derive the quadratic formula from this form.

Solve quadratic equations by inspection (e.g., for x^2 = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.

How Do You Find the a, b, and c Values of a Quadratic Function?
When you're dealing with quadratic equations, it can be really helpful to identify a, b, and c. These values are used to find the axis of symmetry, the discriminant, and even the roots using the quadratic formula. It's no question that it's important to know how to identify these values in a quadratic equation. This tutorial shows you how!
