A.SSE.A.2-1 - Use the structure of a linear, exponential, or quadratic 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).

A.SSE.B.3a - Factor a quadratic expression to reveal the zeros of the function it defines. *(Modeling Standard)

A.REI.B.4 - Solve quadratic equations in one variable.
