Insert your equation however you want and find plenty of information about your equation. weather your equation in standard or factored form, you can find both; x-intercepts, real or imaginary; If it is in factored, find it in standard form; coordinates of the vertex; any coordinate on your graph; and even see your equation on a graph; and more. Enjoy!
This took me a lot of time to make, but I think it was worth it and can be very helpful for plenty of people with home work or just want to play with quadratic equations, so please like/love and tell others about it. EDIT** I added derivative and solving for tangent slope. I haven't quite learned that in school so I went off of a short summary of what it is by my teacher. If there is anything wrong, please tell me!
