How Do You Find The Discriminant of a Quadratic Equation?

The Discriminant

The Discriminant When does ax2+bx+c=0 have a real solution? Well, we know how to find the solutions using the quadratic formula: x=−b±√b2−4ac2a. That makes it look like we can always get solutions. However, we can’t always exercise a square root! Sometimes you’ll see a negative number under the radical. A negative under the radical means there is no real … Read more

Relations and Functions – Explanation & Examples

Relations and Functions

Relations and Functions are the most essential topics in algebra. Relations and functions – these are the two different words having separate meanings mathematically. You might get confused about their difference. Before we go deeper, let’s understand the variation between both with a simple example. An ordered pair is described as (INPUT, OUTPUT):  The relation … Read more
