The expression "a minus b whole square" can be written mathematically as:

(a−b)2(a-b)^2(a−b)2

This means you take the difference between aaa and bbb, then square the result.

Expanded form:

Using the algebraic identity (x−y)2=x2−2xy+y2(x-y)^2=x^2-2xy+y^2(x−y)2=x2−2xy+y2, we get:

(a−b)2=a2−2ab+b2(a-b)^2=a^2-2ab+b^2(a−b)2=a2−2ab+b2

If you want, I can help with examples or further explanations!
