    Take the coefficients of each term and list them.

    - 1 5 - 9

    Multiply 3 by the first coefficient and combine it from the second.

    - 1 * 3 = - 3, 5 - 3 = 2

    Multiply 3 by this product and combine it from the third term.

    3 * 2 = 6, - 9 + 6 = - 3

    Your remainder is option B, - 3.
