See a solution process below:

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

#5t^2 + 7 + t^2 - 3t - 6#

Next, group like terms:

#5t^2 + t^2 - 3t + 7 - 6#

Now, combine like terms:

#5t^2 + 1t^2 - 3t + 7 - 6#

#(5 + 1)t^2 - 3t + (7 - 6)#

#6t^2 - 3t + 1#
