What is a Quadratic Equation?
A quadratic equation is a second-degree polynomial equation, meaning the highest exponent of the variable xxx is 2. It is expressed in the standard form:
ax2+ bx+c=0
Where:
- a, b, and ccc are constants,
- a is the coefficient of x2,
- b is the coefficient of x,
- c is the constant term.
The solutions to the quadratic equation are the values of xxx that make the equation true. These solutions are also known as the roots of the equation.

Quadratic Formula
To solve a quadratic equation, we use the quadratic formula:
x =-bb2-4ac2a
Where:
- b2-4ac is known as the discriminant.
- The term indicates two solutions generally: one with addition and one with subtraction.
Example;
Let’s use an example to illustrate how the Quadratic Equation Solver works.
Problem: Solve the quadratic equation 2x2-4x-6=0.
Solution
- Identify Coefficients: Here, a= 2,b=-4, and c=-6.
- Calculate the Discriminant:
Discriminant = (-4)2-4x2x(-6)2
Discriminant = 16+48
Discriminant = 64
- Apply the Quadratic Formula:
x =-bDiscriminant2a
x =-(-4)642 x 2
x =484
- Solve for x:
x1 = 4+84=124=3
x2 = 4-84=-44=-1
Result: The solutions to the equation 2x2-4x-6=0 are x = 3, and x =-1.
