本帖最后由 高旭明 于 2023-5-20 20:55 编辑今晚的直播课已经结束了，有30位同学参与了我们的直播Tonight's online lesson has ended, with 30 students participating in our lesson.
本次直播课内容为二次方程的7类题型：直接求根、换元法求二次方程、有无实数根问题、同解问题、根系关系（韦达定理）、整数解问题以及无理数根的特殊情况。对每个题型都做了总结，把这些都掌握了，相信不管怎么考大家都不会有问题了。给每位坚持下来的同学点赞
The content of this session focused on the 7 types of question formats related to quadratic equations: direct root finding, substitution method for quadratic equations, problems with existence of real roots, identical roots problems, relationships between roots and coefficient (Vieta's theory), integer solution problems, and special cases of irrational roots. We summarized each question, and if you have mastered them, I believe you will have no problem in any kind of Quadratic equation question. Every student who completed the course is fantastic. Feel free to ask me any questions you have. For some questions, we didn't go through the calculations for the final answers. We encourage you to redo these example questions on your own. After redoing the examples and completing the practice, please send them to me for checking. The exams are approaching, whether you are participating or not, keep it up and strive to improve our mathematical abilities, which is our ultimate goal.
