Help me simplify this expression

I am unable to simplify this expression, help me in this regard, thanks in advance.
I tried this : Normal//ToRadicals//FullSimplify

5 - RootSum[
  5 + 6 #1^2 + 6 #1^3 &, (
   5 Log[1 - #1] - 5 Log[1 - #1] #1 + 11 Log[1 - #1] #1^2)/(
   2 #1 + 3 #1^2) &] + 
 RootSum[5 + 6 #1^2 + 6 #1^3 &, (
   5 Log[-#1] - 5 Log[-#1] #1 + 11 Log[-#1] #1^2)/(2 #1 + 3 #1^2) &]

ComplexExpand[Re[ToRadicals[expr]],TargetFunctions -> {Re, Im}] // Simplify
