Complete the sentence by selecting the correct phrase. The expression (a2−)2−(b2)2 is an example of: a system of equations, a polynomial of degree 2, a difference of squares, an exponential function?

Respuesta :

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.
