This is a java code that takes a quadratic function as input and returns the solution.
Enter your function as ax^2 + bx + c = 0 For example: 5x^2 - 9x - 2 = 0 output will be x = 2 and x = -0.2
also you can put numbers after equal sign: For example: 2x^2=-8x output will be x = 0.0 and x = -4.0
BUT it does NOT accept fractional numbers as input. it WILL GIVE YOU WRONG ANSWER. in next update I will add this feature. For example: 2.5x^2 - 8.5x + 1.35 = 0 output will be x = 2.9041594578792296 and x = 0.4958405421207705 but it's WRONG.
And it does NOT accept parentheses as input. For example: (x + 3)^2=0 output will be: It's not a quadratic function. but it is.
