in this exercise, we're going to simplify the expressions for a B squared minus a B squared. Okay, so it's easy to recognize immediately. Four is a perfect square. B squared is a perfect square, so we can fact those both out of the radical as to be in there. We are left with a inside the radical. Ah, And then, of course, this b squared can also be factored out. So with this well, it wouldn't be radical. A So now we simply have to be radical. A minus be radical. A. So that means our final answer is simply be radical.
