I have a very important test (mathematics).
I need help with quadratic equations and trapezoid calculator, I can't understand them and in my textbook is very very poorly explained. Can somebody give me a link for a tutorial or write something please?
Had no idea what a "trapezoid Calculator" is, so I googled, which you could have done as well.
