    Sure. So you start by multiplying everything out. Then canceling like factors and you get the first and third choice.

    Another easy way to figure this out really fast is by looking at the options that are give. You can then determine that the only possible restriction is x can't equal 1. Everything else works.

    So plug it into your calculator, and plug x=1, You'll not get a solution there, since there is a vertical asympotoe.

    The b in the denominator is a typo, a mistake. There is no answer with a b in it, therefore no solution exist. But if you replace the "b" with a "n" you get the second choice that is listed.
