For a long period of time, folks believed the number system was incomplete and wanted some new form of numbers to complete it, as there was no Option to the equation x2+a=0(where by a>0) in serious numbers, but we now know by the elemental theorem of algebra that every polynomial of degree n has to have n roots. So there need to be a brand new sort of variety required to find the solution to the above mentioned equation.
