This is sort of a math question and it isn't. I just bought this calculator yesterday, and the book that came with it does not tell me how to program the Quadratic formula as well as other equations into this calculator. And someone I know in my class has the same one and told me that this can be done. I was wondering if anyone knows how to program this formula in so that when I plug in the numbers it can be solved, I would prefer to program this myself so I don't have to take it somewhere, but I don't know how to do it.
