Exam August 2019, Problem 8a, phi2

This step is unclear to me:
AGa & AG(Fa & b)
= AG(Fa & b)

Shouldn't it be (?):
AGa & AG(Fa & b)
= AG(a & b)

As AGa should hold, AGFa is trivial, right?

You are right. AGa & AG(Fa & b) = AG(a & Fa & b) = AG(a & b); an update of the example solution has been made.
