See a solution process below:

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

#6h^3 + 5h^2 + 2 - 4h^2 + 9h^3 - 7#

Next, group like terms:

#6h^3 + 9h^3 + 5h^2 - 4h^2 + 2 - 7#

Now, combine like terms:

#(6 + 9)h^3 + (5 - 4)h^2 + (2 - 7)#

#15h^3 + 1h^2 + (-5)#

#15h^3 + h^2 - 5#
