Answer 3

Well, negative three plus the square root of five equals 0.7639320225002103. Let's go ahead and round that to 0.76. Then you would divide 2 by 0.76 in order to get 2.631578947368421. Let's go ahead and round again to get 2.63. I don't know exactly what you are asking, but if you were looking to for a solution, there you go.
