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 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

What are the Key Differences Between DNA and RNA?


The nucleic acids ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) are among the most important molecules in cell biology, which are responsible for storing and transmitting genetic information in all living things. Despite the fact that they are both linear polymers containing sugars, phosphates, and bases, there are a few key differences between them. Both … Read more
