Great news! You can figure out how many roots a quadratic equation has by using something called the discriminant.

A quadratic equation looks like this:
(ax^2 + bx + c = 0).

The discriminant is found using this simple formula:
(D = b^2 - 4ac).

This special formula helps you understand what kind of roots your equation has.

Here’s how it works:

1. If the Discriminant is Positive ((D > 0)):

   • You get two different real roots!
   • This means the quadratic line crosses the x-axis at two different spots. Yay!

2. If the Discriminant is Zero ((D = 0)):

   • You have one real root or a repeated root.
   • This means the quadratic touches the x-axis at just one point, making a perfect square. How cool is that?

3. If the Discriminant is Negative ((D < 0)):

   • You will have two complex roots.
   • This means the quadratic does not touch the x-axis at all, but there are still roots in the complex number area!

Using the discriminant is like having a magic tool for quadratic equations, helping you explore the amazing world of roots!
