See a solution process below:

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

#1.5n^4 + 1.1 - 1.5n + 7.2n + 4.3#

Next, group like terms:

#1.5n^4 - 1.5n + 7.2n + 1.1 + 4.3#

Now, combine like terms:

#1.5n^4 + (-1.5 + 7.2)n + (1.1 + 4.3)#

#1.5n^4 + 5.7n + 5.4#
