$= 12 r - 32$ $= 12r -32$

$4 (3 r - 8)$ $4 (3r -8)$

$= 4 \cdot (3 r - 8)$ $= color(blue)(4) * (3r -8)$

$4$ $color(blue)(4$ is multiplied with each of the two terms within the bracket.

$= 4 \cdot (3 r) + 4 \cdot (- 8)$ $= color(blue)(4) * (3r ) + color(blue)(4) * (-8)$

$= 12 r - 32$ $= 12r -32$
