See the entire solution process below:

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

#3x^2 + 4x - 10 - 2x - 7 + 4x^2#

Next, group like terms:

#3x^2 + 4x^2 + 4x - 2x - 10 - 7#

Now, combine like terms:

#(3 + 4)x^2 + (4 - 2)x - 17#

#7x^2 + 2x - 17#
