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:

#2x^3 - 5x^3y^2 + x^2 - 6x^3y^2 + 3x^2#

Next, group like terms:

#2x^3 - 5x^3y^2 - 6x^3y^2 + x^2 + 3x^2#

Now, combine like terms:

#2x^3 - 5x^3y^2 - 6x^3y^2 + 1x^2 + 3x^2#

#2x^3 + (-5 - 6)x^3y^2 + (1 + 3)x^2#

#2x^3 - 11x^3y^2 + 4x^2#
