Group and combine terms with the same exponents for #f#
to get
#color(white)("XXXX")# #2f^2-4f+3#

Explanation:

#color(red)(-4f^2)color(green)(-6f)color(blue)(+4)color(red)(+6f^2)color(green)(+2f)color(blue)(-1)#

#color(white)("XXXX")##= color(red)(-4f^2+6f^2)color(green)(-6f+2f)color(blue)(+4-1)#

#color(white)("XXXX")##=color(red)(2f^2)color(green)(-4f)color(blue)(+3)#
