By using an argument filtering and a montonic ordering, at least one Dependency Pair of this SCC can be strictly oriented.

F2(f2(a, b), x) -> F2(b, f2(a, f2(c, f2(b, f2(a, x)))))
F2(f2(a, b), x) -> F2(b, f2(a, x))
F2(f2(a, b), x) -> F2(c, f2(b, f2(a, x)))
Used argument filtering: F2(x1, x2)  =  x1
f2(x1, x2)  =  x1
a  =  a
b  =  b
c  =  c
Used ordering: Quasi Precedence: a > b a > c
