Geometric Proof of Perfect Square Trinomial (a+b)^2

Описание к видео Geometric Proof of Perfect Square Trinomial (a+b)^2

The most common mistake high school math students make is thinking that (a+b)^2 is equal to a^2 + b^2. If you watch this geometric proof, you will see why that is obviously wrong and you will clearly see why it is equal to a^2 +2ab + b^2. Hope you enjoy!
