I have the following equation and I solve it using the Function "Solve" and the answer is as follows

Is there any way to sort the roots in order to apply later the function "roots"? Or is there anyway to get the roots out of this Answer = RootOf(.......
I have all the variables at the end but they are quite a lot that's why I have to solve it generally before and then apply for loop to get the roots.
Many thanks in advance
