What Is a Quadratic Equation?

A quadratic equation is a second-degree polynomial equation that plays a major role in algebra and higher mathematics.

Definition of a Quadratic Equation

A quadratic equation is any equation that can be written in the form:

ax² + bx + c = 0, where a ≠ 0

Examples:

• x² − 7x + 10 = 0

• 2x² + 5x − 3 = 0

Standard Form of a Quadratic Equation

The standard form helps identify the coefficients:

• a → coefficient of x²

• b → coefficient of x

• c → constant term

Understanding this form is essential for solving quadratic equations correctly.

What Is a Quadratic Equation Maths Solver?

A Quadratic Equation (Maths solver) is a digital tool that automatically solves quadratic equations using one or more mathematical methods. It provides fast and accurate results, often with step-by-step explanations.

Purpose of a Quadratic Equation Solver

The solver helps users:

• Find roots of quadratic equations

• Understand solving steps

• Avoid calculation errors

• Save time during exams or homework

It is widely used by students, teachers, and professionals.

Methods Used to Solve Quadratic Equations

A Quadratic Equation Maths Solver can apply different methods depending on the equation.

Factoring Method

The equation is factored into two binomials and set equal to zero.
Example:
x² − 5x + 6 = 0 → (x − 2)(x − 3) = 0

Completing the Square

This method rewrites the equation into a perfect square form and is useful when factoring is difficult.

Quadratic Formula Method

The most universal method, using the formula:

x = (−b ± √(b² − 4ac)) / 2a

Graphical Method

The solutions are the x-intercepts of the parabola formed by the equation.

How a Quadratic Equation Maths Solver Works

Step 1: Entering the Equation

Users input the quadratic equation in standard or expanded form.

Step 2: Selecting the Solving Method

Some solvers automatically choose the best method, while others allow manual selection.

Step 3: Calculating the Roots

The solver computes the roots using accurate mathematical rules.

Step 4: Displaying the Final Answer

The result is displayed clearly, often including:

• Exact solutions

• Decimal approximations

• Step-by-step explanations

✔️ Example Output:
x = 2, x = 3

Types of Solutions of Quadratic Equations

Quadratic equations can have:

• Two real solutions (positive discriminant)

• One real solution (zero discriminant)

• Two complex solutions (negative discriminant)

A maths solver identifies and explains each case automatically.
