Answer:
c^4 + 8c^3 - 3c^2 - 7c
Step-by-step explanation:
Simplify (−3c 4 −5c 2 −7c) + (4c 4 +8c 3 +2c 2 ),
Which will take you the second portion of -3c^4 - 5c^2 - 7c + 4c^4 + 8c^3 + 2c^2
Combine like terms : 3c^4 + 4c^4 + 8c^3 - 5c^2 + 2c^2 - 7c
Add Similar elements: c^4 + 8c^3 - 5c^2 + 2c^2 - 7c
Do the final combining leaving you with the answer of :
c^4 + 8c^3 - 3c^2 - 7c
