大家好，本期视频给大家带来的是AP 数学 -分章讲解 5.5 多项式不等式。余下的章节火热更新中，敬请期待！ Hello everyone! In this video, we will look at AP Pre-Calculus – 5.5 Solving Factorable Polynomial Inequality. The rest of the chapters are coming soon, so stay tuned! 章节5.5讨论的是多项式不等式，我们介绍了2种解不等式的方法，分别是图像法和代数法。代数法可以使用表格来帮助我们解不等式 Section 5.5 discusses polynomial inequalities. We introduced two methods for solving inequalities: the graphical method and the algebraic method. The algebraic method can use a table to help us solve the inequality.
