The Quadratic Formula

Making the Boring Beautiful

The Formula

The quadratic formula is universally used to find the roots of a second-degree polynomial equation:

Roots
The roots are the values of that satisfy the equation .

Curiosity: The "Bhaskara" Name

Brazilian Uniqueness

• In Brazil, this formula is widely known as "Bhaskara's Formula", named after the 12th-century Indian mathematician Bhaskara II.

• Interestingly, this naming convention is unique to Brazil; in the rest of the world, it's simply the "Quadratic Formula".
