See the entire solution process below:

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

#3x^3 + 10x + 5 - x^3 + 4x - 6#

Next, rewrite the expression grouping like terms in descending exponential order:

#3x^3 - x^3 + 10x + 4x + 5 - 6#

Now, combine like terms:

#(3 - 1)x^3 + (10 + 4)x - 1#

#2x^3 + 14x - 1#
