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.

Coefficient a must be non zero

Unit tests

Unit tests can be run using command python -m unittest
