I don't know if 2a² or 14a² - 10. Or if they are both wrong.

i am assuming you mean
(7a-5)²
49x²-70x+25
or if it is
2a(7a-5)
14a²-10a

As it is there is nothing more that can be done to the problem.
Are you sure you didn't mean 2(7a-5) or 2a(7a-5)? From your suggested answers it seems that you are trying to do one of those, but I'm not sure.
If it is 2(7a-5) then multiply (2 * 7a) and add (2 * -5).
(2 * 7a) + (2 * -5) =
14a + (-10) =
ANSWER: 14a - 10
If you mean 2a(7a-5) then multiply (2a * 7a) and add (2a * -5)
(2a * 7a) + (2a * -5)=
14a^2 + (-10a)=
ANSWER: 14a^2 - 10a

7a-5 = 7a-5.
You cannot simplify it.
