Raman derived an equation to denote distance of a Haley's comet x in the form of a quadratic equation. Distance is given by the solution of quadratic equation x2+Bx+C=0. To determine constants of the above equation for Haley's Comet, two separate series of experiments were conducted by Raman. Based on the data of the first series, value of x obtained is 1,8and based on the second series of data, value of x obtained is 2,10. Later on it is discovered that first series of data gave incorrect value of constant C while second series of data gave incorrect value of constant B. What is the set of actual distance of Haley' Comet found by Raman?
