Opps, just noticed you want symbolic solution.
Mathematica 8.04 does not do it. I doubt this can be solved symbolically.
Need to use some numbers for the parameters.

Clear[A0, B0, a , C0, D0 , b]
eq = A0 + B0 + x^a (C0 - D0 x^b) == 0
Solve[eq, x]

Solve::nsmet: This system cannot be solved with the methods available to Solve. >>
