Not every equation will start out in these forms, but you'll be able to use the tricks from the last section to get them there.

With these forms, we'll just need one big thing to finish them off:

THE POWER OF INVERSES!

Let's review for a minute:

What do inverse functions do to each other?

If you don't know that off the top of your head, go back and review that stuff or you're going to be one miserable puppy!

OK, what do inverse functions do to each other?

They undo each other!

Remember that

So,
