18t%5E2-128

Take out a factor of 2:
2%289t%5E2-64%29

9t%5E2-64 is the difference of two squares that factors to %283t%2B8%29%283t-8%29 so the entire factorization is:

2%283t%2B8%29%283t-8%29

Factor:
18t%5E2-128 First, factor a 2.
2%289t%5E2-64%29 Now you can see that the paretheses contain the difference of two squares (%283t%29%5E2-%288%29%5E2) which is factored like this:
A%5E2-B%5E2+=+%28A%2BB%29%28A-B%29, so...
2%289t%5E2-64%29+=+2%283t%2B8%29%283t-8%29
