### Core Content Standards

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 \((x^2 – y^2)(x^2 + y^2)\).

### Related Standards

CCSS.Math.Content.HSA.SSE.A.1.b Interpret complicated expressions by viewing one or more of their parts as a single entity. For example, interpret \(P(1+r)^n\) as the product of \(P\) and a factor not depending on \(P\).

### Standards for Mathematical Practice

CCSS.Math.Practice.MP1 Make sense of problems and persevere in solving them.

CCSS.Math.Practice.MP7 Look for and make use of structure.

CCSS.Math.Practice.MP8 Look for and express regularity in repeated reasoning.
