I have a general understanding how to use all the methods of finding the solutions to a quadradic equation but , i really feel like im missing something.

anyone can teach someone to press a button when asked . (apply the formula)
i wanna know what exactly im doing when i press that button .

what is a quadradic? its purpose ? what it looks like ?

my teacher tells me to use these methods and i learn them apply them and get a right answer but then i forget it all in a month ...if i really understood it i think it would stick in my head.
