See a solution process below:

To simplify this expression, multiply each term within the parenthesis by the term outside the parenthesis:

$- 4 (3 u^{2} - 2 u) \Rightarrow$ $color(red)(-4)(3u^2 - 2u) =>$

$(- 4 \times 3 u^{2}) - (- 4 \times 2 u) \Rightarrow$ $(color(red)(-4) xx 3u^2) - (color(red)(-4) xx 2u) =>$

$- 12 u^{2} - (- 8 u) \Rightarrow$ $-12u^2 - (-8u) =>$

$- 12 u^{2} + 8 u$ $-12u^2 + 8u$ .

How do you simplify -4( 3u ^ { 2} - 2u )−4(3u2−2u)-4( 3u ^ { 2} - 2u )?
