Toán 12 | Cực trị hàm số bậc 2 chia bậc nhất chứa tham số m (Dễ hiểu nhất) | Thầy Hùng (Buổi 13)

Hello students! Continuing our series of Grade 12 Math lectures, in today's Session 13, Mr. Hung from Mathchem Center will guide you through a challenging problem type that often causes confusion in exams: Extrema of quadratic functions divided by linear functions containing the parameter m. The function $y = \frac{ax^2+bx+c}{dx+e}$ always requires extreme care in calculating derivatives and determining signs. Especially when the problem incorporates the parameter $m$, if you don't have a firm grasp of the methods and tricks, you can easily lose points or waste too much time. 📌 Main content of the lesson: • Reviewing the formula for quickly calculating derivatives for quadratic functions divided by linear functions. • Conditions for a function to have two extreme points and how to write the equation of the straight line passing through those two extreme points. • Detailed solutions to multiple-choice exercises containing the parameter $m$ from basic to advanced levels, pointing out common mistakes students make. 📖 Link to download materials/exam questions for Session 13: https://drive.google.com/file/d/1JLjf... Remember to prepare scratch paper and practice calculating derivatives with the teacher as you learn!
