Answer: - x^2 + 8x - 12

Explanation:

The given expression is

(3x^2+2x−9)−(4x^2−6x+3)

The negative sign in front of the second parentheses reverses each sign inside. The expression becomes

3x^2 + 2x− 9 − 4x^2 + 6x - 3

By collecting like terms, it becomes

3x^2 - 4x^2 + 2x + 6x - 9 - 3

- x^2 + 8x - 12
