See a solution process below:

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

#10x - 3 + 7x^2 + x^3 - 2x + 17#

Next, group like terms in order of the largest to smallest exponent:

#x^3 + 7x^2 + 10x - 2x - 3 + 17#

Now, combine like terms:

#x^3 + 7x^2 + (10 - 2)x + (-3 + 17)#

#x^3 + 7x^2 + 8x + 14#
