See the entire solution process below:

#### Explanation:

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

$3 {x}^{3} + 10 x + 5 - {x}^{3} + 4 x - 6$

Next, rewrite the expression grouping like terms in descending exponential order:

$3 {x}^{3} - {x}^{3} + 10 x + 4 x + 5 - 6$

Now, combine like terms:

$\left(3 - 1\right) {x}^{3} + \left(10 + 4\right) x - 1$

$2 {x}^{3} + 14 x - 1$
