AOPS Algebra 1 Online Course, Lesson20 , 03/15/2020

In today’s class, students continued to work on the special factorization, such as the sum and difference of cubes and their applications in factoring, simplifications, number computations, and importantly the rationalization of denominators. I strongly ask students to remember those formulas. With the information in their mind, people would pick up the knowledge quickly and form an effective method to solve problems, besides, it may cause less mistakes.  
Again, solving problem is not the only goal, grasping the core in any question and applying the ideas to other questions are what students should keep pursuing in their studying.
Here is the homework to cover today’s contents:
P.343, 11.3.1, 11.3.2, 11.3.3, 11.3.4(a)

P.348, 11.4.1, 11.4.2, 11.4.3, 11.4.4
