What I know is that if the above said equation has three equal roots that meant that the above equation can be written as (x-q)^3*(x-w)*(x-e)... Now do we have to compare this equation with the given one to find the conditions( taking sum of roots at a time,two at a time,three at a time,four at a time,five at a time) or is there any other way to solve such questions.. Any help will be useful...Thanks in advance......
