❖ Geometrical Explanation and Derivation of a square minus b square which is a^2-b^2=(a+b)(a-b)
a^2-b^2, which it called difference of two squares.
Visualize a^2-b^2=(a+b)(a-b) geometrically!
Area of square = side x side
This means you multiply the side length by itself.
Area of rectangle = Length x Breadth.
This means you multiply the length by the breadth (two adjacent sides).
So, we have explained a square minus b square by using geometrical drawings.
