What were Hannibal's mistakes?

By his own admission, Hannibal's failure to attack Rome was his greatest mistake. Had he assaulted the capital after Trasimene, either as a genuine effort or as a feint, Rome would have been forced to recall some of its legions from abroad, exposing Sicily, Spain or Sardinia to a Carthaginian invasion.

What tactics and ideas did Rome adopt?

Explanation:

1.3x - 2 - (3.3x + 5) = 2x + 1

1.3x - 2 - 3.3x - 5 = 2x + 1

-2x - 7 = 2x + 1

-7 = 4x + 1

-8 = 4x

x = -2
