See a solution process below:

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

#9g^2 + 3g + 9 - 3g - 1#

Next, group like terms:

#9g^2 + 3g - 3g + 9 - 1#

Now, combine like terms:

#9g^2 + (3 - 3)g + (9 - 1)#

#9g^2 + 0g + 8#

#9g^2 + 8#
