add equation (5x^8 -5z^4+5z^2+3)+(3z^6+4 z^4-9z) simplify answer to sum
just add like terms:
5x^8 -5z^4+5z^2+3
+3z^6+4z^4-9z
-----------------------------
5x^8 + 3z^6 - z^4 + 5z^2 - 9z + 3
I suspect you meant z^8 and not x^8.
5x^8 -5z^4+5z^2+3
+3z^6+4z^4-9z
-----------------------------
5x^8 + 3z^6 - z^4 + 5z^2 - 9z + 3
I suspect you meant z^8 and not x^8.
