Answer:
a difference of squares
Step-by-step explanation:
Let's write down the expression:
[tex](a^2)^2 -(b^2)^2[/tex]
we can see that this expression is one of the form [tex]x^2 -y^2[/tex] which is the general expression of a difference of squares.
To be more specific and to see why we say this, let's make [tex]x=a^2[/tex] and [tex]y=b^2[/tex]
Now, if we substitute this in the general formula, we get:
[tex]x^2 -y^2 =(a^2)^2 -(b^2)^2[/tex]
Thus, this expression is a difference of squares.
