Simplify: 
(X^4 - 9X  + 5X^7)  + (5X - 10 + 3X^4 - 2X^2)

= X^4 +   - 9X + 5X^7 + 5X +  - 10  + 3X^4 +   - 2X^2

Combine Like Terms:
= X^4 +  - 9X + 5X^7 + 5X +  - 10 + 3X^4 +   - 2X^2

= (5X^7) + (X^4 + 3X^4) + (- 2X^2) + (- 9X + 5X) + (- 10)

= 5X^7 + 4X^4 +   - 2X^2 +   - 4X +   - 10

Answer is: 5X^7 + 4X^4 - 2X^2 - 4X - 10
