+# Quadratic equation solver
+
+![image](img.png)
+
+## Requirements
+```powershell
+numpy : 1.24.2
+matplotlib : 3.6.3
+ttkbootstrap : 1.10.1
+tkinter: "inbuilt", 8.6
+```
+
+A simple quadratic equation solver with ttkbootstrap as GUI
+
+- A Quadratic class was created to ease GUI use
+
+## `Class Quadratic`
+A quadratic class recieves 3 arguments (a,b,c) according to 
+ax² + bx + c
+```python
+q1 = Quadratic(a = 2, b = 4, c = 5)
+```
+## Methods
+### The solve quad method solves a quadratic expression assuming the expression is equal to 0  
+ > returns a tuple of two numbers
+ ```python
+ q1 = Quadratic(a = 1, b = 8, c = 16)
+ print(q1.solveQuad())
+
+ # returns 4, 4
+ ```
+ > Where the determinant is less than zero, a complex number solution is returned `python3 supports complex numbers`
+
+### The evaluate method replaces the x in  ax² + bx + c with an integer or float and returns the calculated value
+ ```python
+ q1 = Quadratic(a = 1, b = 8, c = 16)
+ print(q1.evaluate(value = 2))
+
+ # returns 36
+ ```
+### The draw figure method draws a quadratic equation graph using numpy and matplotlib 
+ > `numpy and matplotlib required` see requirements section above
+ ```python
+ q1 = Quadratic(a = 1, b = 8, c = 16)
+ print(q1.drawFigure())
+
+ # returns 4, 4
+ ```
+ > A matplotlib figure is  returned and can be added to a matplotlib graph
