So times minus 1, times this whole thing, x to the fourth plus 27, to the, we decrement this by 1 more, so minus 2. So let's see if I can simplify this expression a little bit. So this is equal to, so this right here is equal to 12x squared over this thing, x to the fourth plus 27. And then let's see, we're going to have a minus here, so it's minus, you multiply these two guys, 4 times 4 is 16. 16x to the third times x to the third is x to the sixth, over this thing squared, over x to the fourth plus 27 squared. That's just another way to rewrite that expression right there, right? To the minus 2, you can just put it in the denominator and make it to a positive 2 in the denominator.
