Only up to a point. You can force Mathematica to show you the forms it
considers during simplification. For example evaluate

Simplify[(1 - x^2)^2/(1 - x^4),
  ComplexityFunction -> ((Print[#]; LeafCount[#]) &)]

I can't see how to do this using the default setting for the
ComplexityFunction (Automatic) but it only affects the final choice, not the
cases which Mathematica considers.
