  No, I am saying either 1) use good old-fashioned algebra with pen and paper to work out what the quartic is and solve it explicitly using the known standard methods for solving quartic equations, or 2) still use algebra to obtain the quartic and then 'roots' to get its roots. OR (not AND) 3) use 'solve' on the original equations to (hopefully) solve them.  That is how you "get those values."
