Hello,

i want to solve the following for q[b], theta is a symbolic coefficient. When I use the solve command it produces a RootOf that i cannot handle by using either allvalues or evalf. I can't use fsolve since there is theta 

472392*q[b]^13+(-10392624*theta+12597120*theta^2)*q[b]^12+(90069408*theta^2+110697192*theta^4-207222624*theta^3)*q[b]^11+(318718800*theta^6-394931376*theta^3-1213796664*theta^5+1269661392*theta^4)*q[b]^10+(-3766288752*theta^5+4657375260*theta^6+957739788*theta^4-1782380376*theta^7+14700393*theta^8)*q[b]^9+(207696*theta^10+6288766560*theta^6-36914598*theta^9-1374185736*theta^5+4234180392*theta^8-9185729832*theta^7)*q[b]^8+(19428192*theta^10-5820095184*theta^9+10977610320*theta^8-6491850624*theta^7-116480*theta^11+1225901952*theta^6)*q[b]^7+(-8848975200*theta^9+5424037888*theta^10+4454542848*theta^8-709841664*theta^7+12076160*theta^11+25600*theta^12)*q[b]^6+(284107776*theta^8-2169162752*theta^9+5185955328*theta^10-14362624*theta^12-3764956416*theta^11)*q[b]^5+(819093504*theta^10+2011156480*theta^12-95922176*theta^9-2311908352*theta^11+5013504*theta^13)*q[b]^4+(-818036736*theta^13-276840448*theta^11+810954752*theta^12-655360*theta^14+36864000*theta^10)*q[b]^3+(-221405184*theta^13+240451584*theta^14+78905344*theta^12-10616832*theta^11)*q[b]^2+(-45088768*theta^15+39190528*theta^14-9437184*theta^13)*q[b]-3670016*theta^15+4194304*theta^16

What should I do? 

Thank you in advance
