See a solution process below:

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

#-t^2 + 4t - 2 + t^2 + 5t#

Next, group like terms:

#-t^2 + t^2 + 4t + 5t - 2#

Now, combine like terms:

#(-t^2 + t^2) + (4 + 5)t - 2#

#0 + 9t - 2#

#9t - 2#
