Answer: 14a^5 + 14a^4 - 10a^3 - 16a
Step-by-step explanation:
All you have to do is distribute the negative through the second half of the equation,
- (10a - 2a^5 - 14a^4) to get - 10a + 2a^5 + 14a^4.
Now you can look to see if you can combine like terms, i.e. terms that have the same degree of "a" in them. 12a^5 and 2a^5 are like terms. - 6a and -10a are also like terms. The other two terms cannot combine with anything as they share no like terms. The final answer is 14a^5 + 14a^4 -10a^3 -16a. Hope I have helped :)
