This video looks at how we can use the discriminant, which is a part of the quadratic formula, to determine the number of real solutions to a quadratic equation.
From Marty Brandl
When solving with the Quadratic Formula, the "discriminant" is the value that helps you figure out the types of solutions. Yes, it does remind me of the word ...
In this tutorial, you learn how to find the discriminant of a quadratic equation, which is used to tell how many x-intercepts / roots / zeros there are, before you even ...
From Magic Monk
Using d=b^2-4ac we can describe the roots of a quadratic equation without finding them. 2 Real and rational, 2 real and irrational, 1 real, or 2 complex.
From Professor Noy
In this video, we show you how to solve tricky quadratic domain and range functions using the discriminant that can't be solved by the inverse method shown in ...
