MAT-HS Targeted Standards (A) Concept: Algebra (SSE) Domain: Seeing Structure in Expressions Cluster: Interpret the structure of expressions
MAT-HS.A-SSE.02 Use the structure of an expression to identify ways to rewrite it.
For example, see x4 – y4 as (x²)² – (y²)², thus recognizing it as a difference of squares that can be factored as (x² – y²)(x² + y²).
