Geometrical Explanation and Derivation of a minus b whole square (a-b)^2=a^2-2ab+b^2
❖ (a-b)^2 (a minus b square or a minus b whole square).
❖ Visualize (a-b)^2=a^2 - 2ab +b^2 geometrically!
❖ The area of a rectangle can be calculated by multiplying the lengths of two adjacent sides,
Area of rectangle = Length x Breadth.
So, we have explained a minus b the whole square by using geometrical drawings.
