5. A generalization of the polynomial ring Z[2] is the ring Z[[2]] of formal power series over Z. Its elements are power series in < (i.e., polynomials of possibly "infinite degree"). See Example 25.8. The polynomial x + 1 is not a unit in Z[c]: there is no polynomial p E Z[<] such that (x + 1)p(x) = 1. Show that 2+1 is a unit in Z[[x]]. Hint: Clearly, the multiplicative inverse of 2 + 1 in the field of...
