I know that there is a shortcut when there are two terms within the bracket but I wonder if there is one for one with 3 terms

Other than noting each time you multiply unlike terms you do this twice, so can just multiply by 2 the first time, I wouldn't say there's many optimisations you can make. These can be done so quickly in your head there's no point grinding over finding the quickest way, though.

Factor out the six, and realize you're really factoring out a six SQUARED. That makes the inside three terms a bit easier to square.
\[(6t^2-18t+12)^2 = \left(6(t^2-3t+2)\right)^2= 6^2 (t^2-3t+2)^2 = 6^2\left((t-1)(t-2)\right)^2\]
And if you wanna go nuts, that last step equals... \[6^2(t-1)^2\cdot(t-2)^2\]
So yeah. Not exactly a walk through a daisy field, but slightly more manageable. :)
