What is the Quadratic formula?
The quadratic formula is one of the three main methods to solve a polynomial equation with an order 2. The formula is easy to memorize and use.
A seconddegree polynomial is ax^{2} + bx + c. The arrangement is descending in terms of exponents.
Since this equation is known as the quadratic equation, its solving formula is also known as the quadratic formula. The quadratic formula is:
The value of the variables is identified from the quadratic equation. Variable a is the coefficient of the x2 known as the quadratic and variable b is the coefficient of the x and is called the linear coefficient.
And c is the constant of the polynomial equation. The √(b^{2} 4ac) part of the formula is called the Determinant. It determines the nature of the roots. The information obtained from its values is:
When the determinant is equal to zero, you get only one root. This means that the second root is also equal to this one.

How to solve the Quadratic equation?
The process of solving the quadratic equation using the formula will be explained ahead. But if you want to try the fast mean for solving the quadratic equation, use the quadratic formula solver.
The process of solving includes the following 5 steps.

Standard form
To apply the quadratic formula correctly, you need to convert the polynomial expression to the standard quadratic form. You can use the vertex form to quadratic form converter for this step.
The standard form, as said before, has the descending degree syntax i.e ax^{2} + bx + c.

Form an equation
Make the quadratic expression an equation by taking it equal to zero. For example ax^{2} + bx + c = 0.

Find the Coefficients
Now, you have to identify the values of the coefficients of x^{2}, x, and the constant value. E.g a, b, and c.

Put the values
For the fourth step, you enter the identified values in the quadratic formula.

Solve
Finally, simplify the formula for the roots. If you find the determinant separately first, it can give you an idea of the nature of the roots in advance and hence verify your answer.
These are the steps you need to carry out. For even more understanding, see the example below.
Example:
Solve for the values of x.
6  4x + 3x^{2}
Solution:
Step 1: Arrange the expression in the standard form.
3x^{2}  4x + 6
Step 2: Make an equation.
3x^{2}  4x + 6 = 0
Step 3: Identify the coefficients.
a = 3
b = 4
c = 6
Step 4: Plug the values in the formula.
Step 5: Simplify.
