... A.SSE.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). Perform arithmetic operations with complex numbers. N.CN.1 Know there is a complex number I ...
