Factorising using the difference of perfect squares (DOPS) expressions

Algebraic expressions are easier to factorise if the known patterns are
recognised and used. One such pattern is the difference of perfect squares.
Algebraic expressions can be factorised when the Difference of Perfect
Squares rule is used in reverse.

This pattern is easier to appreciate if we look at physical patterns.
Let's look at how the X.Y. Algebra shop is organising the space for their
fruit and vegetable display.
