To simplify the expression a^2 + 5a - 3a^2, you can combine like terms.

The terms with a^2 are -3a^2 and a^2. When you subtract 3a^2 from a^2, you get -2a^2.

The terms with a are 5a and 0. When you add 5a to 0, you get 5a.

So, the simplified expression is -2a^2 + 5a.

Therefore, the correct option is: O - 2a^2 + 6a.
