## Who wrote the quadratic formula?

René Descartes

The quadratic formula covering all cases was first obtained by Simon Stevin in 1594. In 1637 René Descartes published La Géométrie containing the quadratic formula in the form we know today.

**How is the quadratic formula formed?**

A quadratic equation is a degree 2 equation that can be written in the form of ax2+bx+c=0, where a, b, c∈R and a≠0. Every quadratic equation has a corresponding quadratic polynomial that you get by changing the “0” to a “f(x)”. Standard form for a quadratic polynomial is f(x)=ax2+bx+c.

**Who is the father of quadratic equation?**

One of his principal achievements in algebra was his demonstration of how to solve quadratic equations by completing the square, for which he provided geometric justifications….Muhammad ibn Musa al-Khwarizmi.

### Why is it called the quadratic formula?

We use the word quadratic because “quadra” refers to a square, and the leading term in a quadratic equation is “squared.” This is consistent with calling a degree three polynomial a “cubic” for the leading term represents a cube. The word for an equation with a leading term of x^4 is “quartic.”

**How do you introduce a quadratic equation?**

Key Takeaways

- A quadratic function is of the form f(x)=ax2+bx+c f ( x ) = a x 2 + b x + c , where a is a nonzero constant, b and c are constants of any value, and x is the independent variable.
- The solutions to a quadratic equation are known as its zeros, or roots.

**What is the purpose of the quadratic equation?**

Quadratic equations are actually used in everyday life, as when calculating areas, determining a product’s profit or formulating the speed of an object. Quadratic equations refer to equations with at least one squared variable, with the most standard form being ax² + bx + c = 0.

#### What is quadratic equation explain?

Quadratics or quadratic equations can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. The general form of the quadratic equation is: ax² + bx + c = 0. where x is an unknown variable and a,b,c are numerical coefficients.

**Who came up with the quadratic formula, and how?**

An Indian national from Brahma-Sphuta-Siddhanta used negative numbers in solving equations in 628 B.C. or in the 7th century. This mathematician, Brahmagupta, is considered to be the first man who invented the quadratic formula as modern people know it today.

**What careers use the quadratic formula?**

There are a wide variety of jobs that use the quadratic equation. Actuaries, mathematicians, statisticians and computer engineers are a few of the directly related jobs that use the quadratic equation. Others include engineers, chemists, physicists and even nurses.

## What are the steps to solve a quadratic formula?

There are four steps in solving quadratic equations by this method: Step 1: Isolate the and terms. Step 2: Make the coefficient on the term equal to . Step 3: Complete the square. Step 4: Solve the equation in step 3 by taking the square root of both sides of the equation. Step 1: Isolate the and terms.

**Why should I know the quadratic formula?**

The quadratic equation is used in the design of almost every product in stores today. The equation is used to determine how safe products are and the life expectancy of products, such as when they can expect to quit working. Designers can then see what needs to be changed in the product to make it last longer.
