standard_description: 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)).
problem_activity: Problem 1
How do the following problems represent differences of two squares? Factor to show the relationships.
$${4x^4-1}$$
$${x^{10}-36}$$
Problem 2
Factor the following functions and name all of the real and complex zeros.
$${18x^4-32}$$
