Answer:
5x^7 + 4x^4 - 2x^2 + 5x - 19
Step-by-step explanation:
Start by copying 5x -10 +3x^4 - 2x^2 here. Next, add x^4 to +3x^4, -9 to -10, and 5x^7:
5x - 10 +3x^4 - 2x^2
- 9 +x^4 + 5x^7
-----------------------------------------
5x - 19 + 4x^4 - 2x^2 + 5x^7
Now rearrange these terms in descending order by powers of x:
5x^7 + 4x^4 - 2x^2 + 5x - 19 (answer)
