And then these x squareds cancel out. This is going to be equal to the limit as x approaches infinity of 4 minus 5 over x over 1 over x squared minus 3. And what's this going to be equal to? Well, as x approaches infinity, 5 divided by infinity, this term is going to be 0. Super duper infinitely large denominator, this is going to be 0. That is going to approach 0. And same argument, this right here is going to approach 0.
