The application solves quadratic equations.
It asks you to enter a, b and c parameters for the equation in the form "ax2+bx+c=0", then it shows each step of the solving process.
The most important restriction here it is that parameter a cannot be 0 (zero) because in this case the equation will not be a quadratic equation.
The a, b and c parameters can be also negative numbers or decimal numbers.
The application shows the graphical representation of the solutions.
