Example of Calculation with the Third Degree Equations Calculator

Imagine you need to solve this equation:
a = 1
b = -6
c = 11
d = -6
📐 Applied formula: Resolution by Cardano method or other numerical techniques.
📊 Result: x = 1, x = 2, x = 3
This means that the equation has three distinct real roots.
📢 Optimize your algebraic analysis with our calculator.

How Does Our Third Degree Equation Calculator Work?

Our calculator follows a simple three-step process:

1️⃣ Data Entry

To calculate a third-degree equation, enter the following information:

• Coefficient a 📈 Represents the cubic term.

• Coefficient b 📉 Quadratic term.

• Coefficient c ⏳ Linear term.

• Coefficient d 💰 Independent term.

Why is it important?
Because the values you enter determine the nature of the roots (real, complex, double or simple).

2️⃣ Automatic Calculation

We use advanced formulas like Cardano's to find cube roots accurately:
📐 Formula: ax³ + bx² + cx + d = 0
The system applies symbolic or numerical methods to solve in real time.

3️⃣ Results and Recommendations

🔹 If the roots are real, you can easily interpret them.
🔹 If the roots are complex, our calculator also shows them to you in detail.
