Computational - pencil and paper ready. Find the radius of a circle described by the equation x squared plus y squared minus 10x minus 2y equals 23. The radius of such a circle can be found by group- ing the x and y terms on the left-hand side of the equation and completing the squares of each group. When adding those two quantities to the left side, don't forget to add them to 23, as well. The square root of your new quantity on the right will give you the radius of a circle described by the given equation. Thirty seconds.
