    The answer is 6x² - 11x - 1

    The expression is:

    (3x² + 3) - (6x + 4) + (3x² - 5x)

    Let's lose parenthesis:

    (3x² + 3) - (6x + 4) + (3x² - 5x) = 3x² + 3 - 6x - 4 + 3x² - 5x

    Now, rearrange:

    3x² + 3 - 6x - 4 + 3x² - 5x = 3x² + 3x² - 6x - 5x + 3 - 4 = 6x² - 11x - 1

    Distributing each of the signs to the binomials, it first simplifies to 3x^{2} + 3 - 6x-4 + 3 x^{2} - 5x. Then you add all of the like terms and get 6x^{2} - 11x - 1.
