I love how you have different videos showing multiple representations for the same concept/skill (e.g. factoring a trinomial with the area model method last week and by grouping this week)! This video was great and I really like how you explain the problem hasn't been changed by re-writing that middle term. Also great how you pointed out you are "factoring out" the x-5 at the end which is why it gets its own set on the left. There are lots of math tutorial channels out there but yours stands out as the BEST one because you help build intuition instead of just memorizing a process - this really sets your channel apart from others!! Really enjoy these weekly videos - thanks for posting them! 👍
