## CCSS.Math.Content.HSA.SSE.A.2 - 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}).

- Use the Structure of an Expression to Identify Ways to Rewrite It - Writing mathematical expressions in different ways is incredibly important, especially in algebra. It's not about redundancy; it's about simplicity. Students should be able to convert mathematical expressions to alternative but equivalent forms by factoring.
