A-SSE.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. 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).
