Answer:
3x^6-x^5+7x^3
Step-by-step explanation:
So we have 3x^6+2x^3, then -x^5+5x^3 (after distributing the negative)
3x^6 cant be added to another number, neither can -x^5 so we can list them as follows
3x^6-x^5
Now 2x^3 and 5x^3 have the same exponent, so you can add them together to get 7x^3
The final solution will be 3x^6-x^5+7x^3 with exponents from highest to lowest.
