# What is theory of quadratic equation?

**Theory of Quadratic Equation**Formulae. The

**theory of quadratic equation**formulae will help us to solve different types of problems on

**quadratic equation**. The general form of a

**quadratic equation**is ax2 + bx + c = 0 where a, b, c are real numbers (constants) and a ≠ 0, while b and c may be zero.

Also, what is the meaning of quadratic formula?

**Definition of quadratic formula**. : a **formula** that gives the solutions of the general **quadratic equation** ax^{2} + bx + c = 0 and that is usually written in the form x = (-b ± √(b^{2} − 4ac))/(2a)

Beside above, what is the history of the quadratic formula? At the end of the 16th Century the mathematical notation and symbolism was introduced by amateur-mathematician François Viète, in France. In 1637, when René Descartes published La Géométrie, modern Mathematics was born, and the **quadratic formula** has adopted the form we know today.

Similarly, what is the purpose of the quadratic equation?

In elementary algebra, the **quadratic formula** is a **formula** that provides the solution(s) to a **quadratic equation**. There are other ways of solving a **quadratic equation** instead of using the **quadratic formula**, such as factoring (direct factoring, grouping, AC method), completing the square, graphing and others.

Who invented quadratic equation?

The Babylonians **came up with** a technique called “completing the square” to solve common problems with areas by 400 BC. The first purely mathematical try to come up with a **quadratic formula** was done by Pythagoras in 500 BC. Euclid did the same thing in Alexandria, Egypt. Euclid used a purely geometric method.
