Subject Area: Algebra
Subject Topic: Expansion of Binomials Squared
Prerequisites: Areas of Square and Rectangle
The visual proof of the expansion of (a+b)^2 starts with a square.
Since, we are expanding (a+b)^2, it may be represented by the area of the square with side (a+b).
Finding all the areas of the regions formed:
Therefore,
