As you take the square root of 6 infinitely and continuously add it to itself, you will slowly approach 1/2 of 6 which is three. You will get closer and closer to three, but the repeating square root prohibits is from getting there.
Let: Now, note that if you square it and move +6 to the LHS: But the RHS is again! Thus, we see that is the positive solution to the quadratic: which is simply 3.
