FOIL Method and Polynomial Expressions

The video tutorial explains how to apply polynomial operations to geometric shapes, focusing on calculating areas and volumes. It covers the use of the FOIL method and shortcuts for multiplying conjugates and squaring binomials. Examples include finding the area of a rectangle and a square, and the volume of a cube, all represented by polynomial expressions.
