Factor this expression completely and then place the factors in the proper location on the grid.

x2 - 9

For this case, we have to define the difference of squares:

We then have the following expression:

From here, we observe that:

Therefore, replacing values we have:

The factorization of the given expression is:

true? is that what you're asking or do you mean something else?

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
