Given an equation like 2/((jw)^2 +54jw +44), how would you find the critical frequency?

Let s = jω and write your equation using s. You should be able to factor the denominator and hence pick out any critical frequencies (I'm assuming that by 'critical frequency' you also mean 'corner frequency' for the Bode plot). (Also, the roots of the denominator should be real).
