The quadratic curve is one of the key contents of high school mathematics. The quadratic curve problem tends to be easy to start, but it is not easy to get the right and the end. It is not easy to obtain the correct and perfect answer. The author combines his common question types and solutions in analytical geometry according to his own teaching practice. Skills, analysis of some typical misclassifications, aiming at multi-angle development of thinking skills, improving the quality of problem solving in all directions. 1 Mismatching students, causing misunderstandings (1
