(3x-8)(1-2x)

Explanation:

Note the terms :
color(white)("XXX")color(orange)(3x)color(red)((1-2x))
and
color(white)("XXX")color(green)(8)color(red)((1-2x))
have a common factor of
color(white)("XXX")color(red)((1-2x))

Therefore
color(orange)(3x)color(red)((1-2x)) - color(green)(8)color(red)((1-2x))

=(color(orange)(3x)-color(green)(8))(color(red)(1-2x))
