    I'd actually recommend using\[\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{ad}{bc}\] first, and then factoring.

    Start factoring and canceling.

    If you will do the numerator, I will do the denominator.

    I got a numerator of higher degree than denominator, so I converted it to a mixed number. I don't think that's necessary though; usually with rational expressions, leaving everything in factored form as improper fractions is more convenient.

    You are looking at the wrong answers. There is not a y in you problem. Please look at the problem you have entered in the problem box!

    I don't agree with C, but then again I don't agree with a lot of things. You will notice that C can be further simplified by a division of x to both numerator and denominator.

    If D were: x(x-1)/3(x+1) It would be more acceptable.
