HSA-SSE.A.2
Use the structure of an expression to identify ways to rewrite it. For example, see x<sup>4</sup> – y<sup>4</sup> as (x<sup>2</sup>)<sup>2</sup> – (y<sup>2</sup>)<sup>2</sup>, thus recognizing it as a difference of squares that can be factored as (x<sup>2</sup> – y<sup>2</sup>)(x<sup>2</sup> + y<sup>2</sup>).
