So this is going to be equal to, this is going to be equal to, let's see, let's multiply, well, the denominator, we know what the denominator is. It is x to the fourth plus 27 squared, that's our denominator, and then we can multiply this out. This is 12x squared times x to the fourth, so that's 12x to the sixth plus 27 times 12, I don't even feel like multiplying 27 times 12, so I'll just write that out. So plus 27 times 12x squared, I just multiply the 12x squared times 27, and then minus 16x to the sixth. And this simplifies to, let's see if I can simplify this even further. So I have an x to the sixth here, x to the sixth here, so this is equal to, I'll do this in pink, this is equal to the 27 times 12x squared, I don't feel like figuring that out right now, times 12x squared, and then you have minus 16x to the sixth and plus 12x to the sixth. So you add those two, you get minus 4, 12 minus 16 is minus 4, x to the sixth, all of that over x to the fourth plus 27 squared.
