The answer should be (3b + 2)(3b - 2) since if you multiply those two, you will get back to original equation.

Hope this helps!

So for this, we will be applying the difference of squares, which is [tex]x^2-y^2=(x+y)(x-y)[/tex]

In this case:

[tex]9b^2-4=(3b+2)(3b-2)[/tex]

The correct answer is the second option.
