Combine like terms to get the answer, #2x^3+10x^2-x-18#.

Explanation:

Let's get rid of the parentheses, since there are no coefficients or negative signs outside of the parentheses:

#4x^2-x-7+2x^3+6x^2-11#

Let's reorganize the equation to combine like terms and solve:

#2x^3+4x^2+6x^2-x-7-11#
#2x^3+10x^2-x-18#
