Let's learn how to complete the square!

I try to teach here how can we complete a square when we are presented with an expanded quadratic polynomial (quadratics). You can download my notes for free without any ads or registration from my shared drive here (before the channel gets verified I am not allowed to post links, so you need to manually remove spaces around the dot, or follow the link in the channel description): https://murena . io/s/68Pd3a7WTJc6Ryo 0:00 Intro 0:38 Introducing quadratics and showing some examples 3:27 Example of expanding a completed square form 5:00 How do we go the other way around? The derivation of the formula (made a mistake in the end, corrected it later at 17:28) 16:04 Example 1 and correcting my mistake 18:41 Example 2 23:30 Following the same process but with numbers 26:40 Outro and explaining the goal behind the channel
