And like always, pause this video and see if you can figure it out. Well, whenever we're trying to find limits at either positive or negative infinity of rational expressions like this, it's useful to look at, well, what is the highest degree term in the numerator or in the denominator, or actually in the numerator and the denominator, and then divide the numerator and the denominator by that highest degree, by x to that degree. Because if we do that, then we're going to end up with some constants and some other things that will go to zero as we approach positive or negative infinity, and we should be able to find this limit. So what I'm talking about, let's divide the numerator by one over x squared, and let's divide the denominator by one over x squared. Now you might be saying, wait, wait, I see an x to the fourth here, that's a higher degree. Remember, it's under the radical here. So if you want to look at it at a very high level, you're saying, okay, well, x to the fourth, but it's under, you're gonna take the square root of this entire expression, so you could really view this as a second degree term.
