See the entire solution process below:

To simplify this expression multiply each term within the parenthesis by $- 4$ $color(red)(-4)$

$- 4 (9 x - 2) \to (- 4 \times 9 x) - (- 4 \times 2) \to$ $color(red)(-4)(9x - 2) -> (color(red)(-4) xx 9x) - (color(red)(-4) xx 2) ->$

$(- 36 x) - (- 8) \to$ $(-36x) - (-8) ->$

$- 36 x + 8$ $-36x + 8$
