  1. Difference of Two Squares – Demonstration This resource provides animated demonstrations of the mathematical method. Check animations and delete slides not needed for your class.

  2. Difference of Two Squares Area = Area = • This rearrangement shows how • we can factorise a square that • has had another square • subtracted from it. A ‘perfect’ square: We subtract another square: What is the area of the new shape? What is the difference of two squares?

  3. Difference of Two Squares Area = Area = = • This rearrangement shows how • we can factorise a square that • has had another square • subtracted from it. A ‘perfect’ square: We subtract another square: What is the difference of two squares?

  4. Difference of Two Squares Area = Area = = If we expand:
