**Introduction:**

The Chinese, Babylonian and the Egyptian engineers came up with the first-ever formula around 2000BC. Around 700AD the general solution for the quadratic equation, this time using numbers, was devised by a Hindu mathematician called Brahmagupta, who, among other things, used irrational numbers; he also recognized two roots in the solution. Bhaskara was the first one to recognize that a post number has two square roots.

This formula allows us to find out the root of a quadratic equation. The development or derivation of a mathematical idea is usually logical, deductible and rectilinear as possible. This so-called quadratic formula has been worked on for ages to sample the present form that we now learn in schools.

**Meaning:**

The Quadratic Equation Calculator determines whether the discriminant is less than, greater than or equal to 0. The QEC has made equations very easy to solve because usually kids and teenagers take time to solve critical equations. Still, with the calculator, it has made their lives easier and faster, due to the calculator never gets wrong and can be reliable.

A quadratic equation is a second-order polynomial equation in a single variable ax2 +bx+c = 0, with a = 0. It is a second-order polynomial equation, the theorem of algebra states that it has two solutions. These solutions may or may not be both real or complex.

**Definitions:**

The quadratic equation calculator allows us to solve a quadratic equation step by step either by finishing the square or using the quadratic formula. It will find both real and imaginary roots of a given quadratic equation.

A Quadratic Equation is a polynomial equation which involves the square of the variable but with no higher powers. In this rule, we can find the solutions of the quadratic equations. Sometimes the solutions can be real numbers, and sometimes they are nonreal.

**Objectives:**

- Solve equations using factoring, square roots, completing the square.

An essential technique for solving such equations is to use factoring or square roots when the form of the equation suggests one of those methods and otherwise utilize the quadratic formula.

- It is designed to work in every browser and OS.

The QEC works in all kinds of web browsers, and it is effortless to understand the Quadratic Formula Solver. It is user-friendly software which helps many of the users. Also, it is very fast in solving the problems and providing the correct answer.

- It is designed to use all kinds of methods to provide an accurate answer.

a. Factoring method.

b. Square root method.

c. Completing the square method.

- Use the discriminant to classify the solutions of a quadratic equation.

The expression which appears within the radical in the quadratic formula is called the discriminant of the expression.

**Pros of using Quadratic Equation Calculator and Quadratic Formula Solver:**

**1.Everyday Usage**

As a student, we will have to deal with Quadratic Equations in Mathematics subject every day. So the calculator makes it easy for us to solve challenging problems faster, also with an accurate answer.

**2.Always Right**

As humans, we can often be wrong about the answer to the problems we calculate. We can be imperfect or miss some calculations, formulas Etc. However, calculators can never be wrong because a machine cannot lie, thus makes us rely on it for the correct answer.

**3.It is Quicker and more manageable.**

As it is a machine it is speedy and does many complex calculations in just a few moments because of the Quadratic Formula Solver it helps in solving the problem which has been entered.

**4.Not only also answers, solutions!**

The best part of the Quadratic Formula Solver is that it just does not provide the answer but also walk us through the problem and gives us the steps, methods and solutions. Most of the lecturers these days do not focus on the correct answer. They want instead to see our approach towards the problem. Many times when we use the simple approach, the teacher may think that either we do not know about the difficult one or us have copied the answer from somewhere. To avoid this, we must also know the steps that are involved in reaching the answer that we have.

**Cons of Quadratic equation calculator and quadratic formula solver:**

The disadvantages of using this calculator may not be significant for someone whose already done studying, though it holds quite a few disadvantages for the students.

**1.Dependency.**

Even though calculators can do the basic operations instantly, students shall not use such calculators as it makes them incapable of solving basic equations and more dependent blurting the brain.

**2.Lack of Creativity.**

There are some studies which state that lately, many people have been using Quadratic equation calculators very much. This can be a problem because shortly, we might lack quality scientists with excellent computational skills. This can be a significant problem because students excessively depend upon these websites and handheld calculators that they are not able to solve the problems without these devices.

**3.Lack of Understanding skills:**

Due to increase in dependancy people try to copy instead of understanding what it is. They lack understanding skills. If this continuous further, chances are higher that they might even forget the basics of the subject.

**Conclusion:**

In the end, all we can understand is that everything has their pros and cons we have to get along with every step of the way. The Quadratic Equation Calculator has made our lives much more manageable. This not only helps us to solve the problems but also shows every step of how the problem is being solved.

The Quadratic Formula Solver is a vital part of solving the problems because it uses those formulas which are necessary for solving the problems.
