So it's going to be 8 over x minus 2x. And let's set that equal to zero. So if we focus on this part right over here, we could add 2x to both sides, and we would get 8 over x is equal to 2x. Multiply both sides by x. We get 8 is equal to 2x squared. Divide both sides by 2. You get 4 is equal to x squared.
