See a solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

#9x^3 + 35x^2 + 11x + 60 + 3x + 12#

Next, group like terms:

#9x^3 + 35x^2 + 11x + 3x + 60 + 12#

Now, combine like terms:

#9x^3 + 35x^2 + (11 + 3)x + (60 + 12)#

#9x^3 + 35x^2 + 14x + 72#
