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

#### Explanation:

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

$4 {x}^{2} - x - 7 + 2 {x}^{3} + 6 {x}^{2} - 11$

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

$2 {x}^{3} + 4 {x}^{2} + 6 {x}^{2} - x - 7 - 11$
$2 {x}^{3} + 10 {x}^{2} - x - 18$
