I would start by factoring each of these expressions.
9s^2 + 30st + 25t^2 = (3s + 5t) (3s + 5t)
25s^2 – 25st – 6t^2 = (5s + t) (5s – 6t)
You figure out the others.
HINT: I highly suspect that you will be able to cross out some of these factors so when you try to factor the last 2 expressions, look to see if any of the above factors will work.

tops: (3s+5t)² (5s-6t)(4s-5t)
bottoms: (4s-5t)(3s+5t)
(3s+5t)(5s-6t)/(5s+t)(5s-6t)=(3s+5t)/(5s+t)
