Example of Calculation with the Second Degree Equations Calculator

Imagine you need to solve the equation: 2x² + 4x – 6 = 0
📐 Formula applied: x = [-4 ± √(4² – 42(-6))] / (2*2)
📊 Result: x₁ = 1, x₂ = -3

This means that the roots of the equation are 1 and -3, so you can factor it as (x – 1)(x + 3) = 0.
📢 Save time on your math homework with our automatic tool.

How Does Our Second Degree Equation Calculator Work?

Our calculator follows a simple three-step process:

1️⃣ Data Entry

Enter the following values for your equation:

• Coefficient a 💰 value that multiplies x²

• Coefficient b ⏳ value that multiplies x

• Coefficient c 📉 independent term

Why is it important?
These three numbers define the nature of the parabola and the type of solution: real or complex.

2️⃣ Automatic Calculation

We use the quadratic formula:
📐 x = [-b ± √(b² – 4ac)] / 2a

The result will tell you the possible solutions to the equation exactly.

3️⃣ Results and Recommendations

🔹 If the result is two real roots, you can graph or factor them.
🔹 If they are complex roots, you will know that the parabola does not cut the X axis.
