step 1. [(3 - (3 + h))/(3(3+h))]/h
step 2. -h/(3(3+h)h
My book says that those steps are valid. I don't see how.
If you want my opinion, I times the numerator (3 - (3 + h))/(3(3+h)) by the inverse of the denominator h/1 which makes:
step 2. -h/(9+3h) * h
step 3. -h/(9+3)
step 4. -h/12
step 2. -h/(3(3+h)h
