Answer:
-g^4 - 10g²h² -3h^4
Step-by-step explanation:
E = -7g^4 + 3g²h² - 11h^4
F = 6g^4 - 13g²h² + 8h^4
-7g^4 + 3g²h² - 11h^4 + 6g^4 - 13g²h² + 8h^4
combine like terms
-7g^4 + 6g^4 = -g^4
3g²h² + (- 13g²h²) = -10g²h²
- 11h^4 + 8h^4 = -3h^4
so we have:
-g^4 - 10g²h² -3h^4
this cannot be simplified any further and this is our answer
