How to find the foci of a hyperbola

The app is great for checking algebra homework, and it also explains it so you can understand it better, the only downside is sometimes when I need an explanation, I have to pay for it- but everyone needs to make money somehow. Only due to this now I solve any algebra very fast without any calculator or other thing.

It's one of the best ever apps for maths problems. But a suggestion is please add the solutions for still more problems and try to show the steps @ Team math app. Excellent calculator for every problem, it also tackles almost every math subject like algebra, calculus, etc. It saves me a bunch of time in my research.

I liked this application very much, a useful, wonderful and easy application, but there is one negative and I think that it is not considered negative as well, which is the lack of diversity of languages, I hope there is the Arabic language to simplify things and thank you, it's able to understand equations from photos very well, although it sometimes has trouble with recognising stuff, which can be easily edited anyways.
