#12n^4-10n^2-2n-12#

Explanation:

#(color(red)(8n^4)color(blue)(-6n^2)color(green)(-4))-(color(blue)(6n^2)color(green)(+4)color(red)(-n^4))+(color(blue)(2n^2)color(red)(+3n^4)color(green)(-4)color(magenta)(-2n))#

#= color(red)(8n^4-(-n^4)+3n^4)+color(blue)((-6n^2)-6n^2+2n^2)+color(magenta)(""(-2n))+color(green)(""(-4)-4+(-4))#

#=12color(red)(n^4)-10color(blue)(n^2)-2color(magenta)n-12color(green)#
