----------
3(1-2t+t^2) -2+2t + 1
----
= 3 -6t +3t^2 -2 + 2t + 1
----
= 3t^2 - 4t +2

Given:f%28x%29+=+3x%5E2-2x%2B1 findf%281-t%29
You're off to a good start!
f%281-t%29+=+3%281-t%29%5E2-2%281-t%29%2B1 Now you need to expand the terms:
f%281-t%29+=+3%281-2t%2Bt%5E2%29-2%2B2t%2B1
f%281-t%29+=+3-6t%2B3t%5E2-2%2B2t%2B1 Now combine like-terms.
highlight%28f%281-t%29+=+3t%5E2-4t%2B2%29
