Answer:=6x3−9c
Step-by-step explanation:
3x3+4x2+3x3−4x2−9c
=3x3+4x2+3x3+−4x2+−9c
Combine Like Terms:
=3x3+4x2+3x3+−4x2+−9c
=(3x3+3x3)+(4x2+−4x2)+(−9c)
=6x3+−9c
That is simplest form
50x+56=50x+56, they are not like terms so you can't add them
if you did want to factor, the common term is 2 so then
50x+56=2(25x+28)
