Answer:
The simplified equation is as follows 2x^5 -x^4 + 9x^2
Step-by-step explanation:
Remove the parentheses around each equation and pair like exponents together
4x^5 - 2x^5 - x^4 + 3x^2 + 6x^2
Then combine the like terms
2x^5 - x^4 + 9x^2
It is in that order due to the proper form being to go from the highest to lowest exponents in an answer
