Examples, solutions, videos, and lessons to help High School students learn to use the structure of an expression to identify ways to rewrite it.*For example, see x*^{4} – y^{4 }as (x^{2})^{2} – (y^{2})^{2}, thus recognizing it as a difference of squares that can be factored as (x^{2} – y^{2})(x^{2} + y^{2}).
