Answer:

$7 {x}^(2) - 2x( - 4 - x) = 9 {x}^(2) + 8x$

Explanation:

We want to simplify

$7 {x}^(2) - 2x( - 4 - x)$

We expand using the distributive property to obtain:

$7 {x}^(2) + 8x + 2 {x}^(2)$

We regroup the terms to get:

$7 {x}^(2) + 2 {x}^(2) + 8x$

We now simplify to get:

$9 {x}^(2) + 8x$

Therefore

$7 {x}^(2) - 2x( - 4 - x) = 9 {x}^(2) + 8x$
