Your question is unclear, so I just got your expanded polynomial instead:

#H(x)=2x^3-24x^2+97x-128#

#H(x) = x-2(4-x)^3#

#=x+2(x-4)^3#

#=x+2color(green)((x-4)(x-4))(x-4)#

#=x+2color(green)((x^2-8x+16))(x-4)#

#=x+2(x^3color(red)(-4x^2-8x^2)+color(blue)(32x+16x)-64)#

#=x+2(x^3color(red)(-12x^2)+color(blue)(48x)-64)#

#=color(red)(x)+2x^3-24x^2+color(red)(96x)-128#

#=2x^3-24x^2+color(red)(97x)-128#
