Question

Hello! so this is java language. i am working on gui java program. this program solves quadratic equations. what i have so far works but not for imageinary numbers. so i want to add codes which will solve imaginary numbers.

example will be if A=1, B=2, C=3. then solution is with imaginary number(giveing in the screenshot). this is what i have so far and solution for imaginary numbers need to looks like it is in the screenshot. (1+2, 12)

Thanks.
