Explanation:
Probably what is giving you the problem is the term opposite. It means that, as in integers, the opposite of any integer is the opposite sign of the given integer.
For example the opposite of 4 is - 4. The opposite of -7 is 7

- ( -4x2 + 5x - 3) = 4x^2 - 5x + 3
I guess that makes it e.
