Well, this we already established is positive two. This we already established, let me do this in the yellow color. This we already established is 1.4, and this part right over here is 0.36. So this is going to be equal to two plus 1.4 times 0.36 is 0.9, or 0.09. So this is going to be equal to, this is going to be equal to 2.09. So that is our approximation, and it should be, at least based on how I graphed it, a little bit higher than the actual value of the square root of 4.36. But we could write that up here.
