As you can see, there are many forms of quadratics formulas in the world we live in. From the arc of a rainbow crossing the sky to a dolphin leaping over the surface of the ocean to even something as mundane as a necklace on someone's neck.

### What is a Quadratic Formula?

A quadratic formula is used to solve for the x-intercept, which is also known as a solution, a root, a solution, or a zero.

People throughout the ages have been using the Quadratic Formula in a variety of useful ways. Such as the Arc De Triomphe found above.

We can even find the Quadratic Formula being put to use practically through architecture.
