# QuadraticEquationSolvePlot

## Quadratic equations made easy!

- Enter the coefficients and let us do the rest.

- We'll show you the assembled equation.

- Calculate the discriminant and roots.

- Visualize the parabola with a graph.

## Visualizes the Solution

This program isn't just limited to solving quadratic equations; it can also visualize them!  The code utilizes the matplotlib library to generate a graph of the equation based on the user's input.  This graphical representation can be particularly helpful in understanding the relationship between the coefficients and the solution's behavior.

## Discriminant - 3 solution are possible

Distriminant: D = b^2 - 4ac

- when dicriminant is positive, equation has two real solutions

- when dicriminant is zero, equation has just one solution

- when dicriminant is negative, equation has two complex solutions

## Solution

### Equation with 2 real roots

D > 0    ->     2 real roots

### Equation with 1 real root

D = 0    ->     1 real root (Root1 = Root2)

### Equation with 2 complex roots

D < 0    ->     2 complex roots

## Input validation

### Only integers

It is possible insert only integers.

## Unit tests

Unit tests can be run using command

python -m unittest
