See a solution process below:

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

#2g^2 + 8g + 9 - g^2 - 5g - 9#

Next, group like terms:

#2g^2 - g^2 + 8g - 5g + 9 - 9#

Now, combine like terms:

#2g^2 - 1g^2 + 8g - 5g + 9 - 9#

#(2 - 1)g^2 + (8 - 5)g + (9 - 9)#

#1g^2 + 3g + 0#

#g^2 + 3g#
