Quadratic Equation Solver (C# Windows Forms)

This is a simple C# Windows Forms application that solves a quadratic equation of the form:

ax² + bx + c = 0 The program takes coefficients a, b, and c as input, calculates the discriminant D = b² - 4ac, and then displays the solutions based on the value of D: ##Logic

• If D > 0 → two real and distinct solutions
• If D = 0 → one real double root
• If D < 0 → two complex (imaginary) solutions

The app is built in Visual Studio (C#) using Windows Forms, with basic input validation and result display using TextBoxes and Labels.

##How to Use

1. Enter values for a, b, and c in the corresponding text fields.
2. Click "Реши" to calculate the solutions.
3. The results will be shown in the lower fields:
   • If real: solutions x₁ and x₂
   • If imaginary: real and imaginary parts
4. Click "Избриши" to clear all inputs and results.
