Quadratic Formula Calculator (Maths solver)
What Is a Quadratic Formula Calculator?
A Quadratic Formula Calculator (Maths solver) is a digital math tool that solves quadratic equations using the standard quadratic formula. It is designed to provide fast, accurate solutions without the risk of manual calculation errors.
Understanding Quadratic Equations
A quadratic equation is written in the standard form:
ax² + bx + c = 0, where a ≠ 0
Examples include:
-
x² − 5x + 6 = 0
-
2x² + 3x − 4 = 0
Purpose of a Quadratic Formula Calculator
The calculator automatically applies the quadratic formula to find the roots of any quadratic equation, making it ideal for students, teachers, and professionals.
How the Quadratic Formula Calculator Works
Knowing how the calculator works improves confidence and understanding.
Step 1: Entering the Coefficients (a, b, c)
Users input the values of a, b, and c from the quadratic equation.
Example:
For x² − 5x + 6 = 0
a = 1, b = −5, c = 6
Step 2: Applying the Quadratic Formula
The calculator uses the formula:
x = (−b ± √(b² − 4ac)) / 2a
Step 3: Evaluating the Discriminant
The discriminant (b² − 4ac) determines the nature of the solutions:
-
Positive → two real solutions
-
Zero → one real solution
-
Negative → complex solutions
Step 4: Calculating the Final Solutions
The calculator outputs one or two solutions, often with step-by-step explanations.
✔️ Example Output:
x = 2, x = 3
Types of Solutions a Quadratic Formula Calculator Provides
Two Real Solutions
Occurs when the discriminant is positive.
One Real Solution
Occurs when the discriminant equals zero.
No Real Solutions (Complex Roots)
Occurs when the discriminant is negative, resulting in imaginary numbers.
