this woulda helped a bunch

Literally, 2 minutes that could have changed my childhood math experience.

Wish someone would have shown this back in algebra days

Such geometrical proofs for algebraic identities like this and (a - b)², a² - b², and others, have long appeared in math textbooks worldwide, especially in middle/high school curricula that link algebra and geometry.

If a = 1 and b =4, then 25 = 25

That's a great visualization!

あ、これいいねえ 中学生からの謎がとけた気がする

Simple tools to teach maths 👏

How can you prove Geometrically if a=-2 type cases

Do for Geometric proof of (a-b)²= a² - 2ab + b²

That's why it's called: PERFECT SQUARE TRINOMIAL

this inspired me to visualise (a+b)^3 ... btw this is such a great way to visualise it. i think i must have skipped my math class when this was being explained (if it ever was ¯\_(ツ)_/¯)

Except it’s not a proof. It’s just a restatement of the problem in a different language.
