Answer:
c4+8c3+−3c2+−7c
Step-by-step explanation:
Let's simplify step-by-step.
−3c4−5c2−7c+4c4+8c3+2c2
=−3c4+−5c2+−7c+4c4+8c3+2c2
Combine Like Terms:
=−3c4+−5c2+−7c+4c4+8c3+2c2
=(−3c4+4c4)+(8c3)+(−5c2+2c2)+(−7c)
=c4+8c3+−3c2+−7c
Answer:
c^4 + 8 c^3 - 3 c^2 - 7 c
Step-by-step explanation:
(− 3c^4 − 5c^2 − 7c) + (4c^4 + 8c^3 + 2c^2)
I like to line them up vertically.
− 3c^4 − 5c^2 − 7c
+ 4c^4 + 8c^3 + 2c^2
--------------------------------------------
c^4 +8c^3 -3c^2 -7c
