    We want to factor 3a² - 5ab - 2b².

    Note that

    (3a) * (-2b) + a*b = - 6ab + ab = - 5ab

    (3a) * a = 3a²

    b * (-2b) = - 2b²

    Therefore

    3a² - 5ab - 2b² = (3a + b) (a - 2b)

    The factors are (3a + b) and (a - 2b).

    Answer:

    One of the factors is (3a + b).

    Another factor is (a - 2b).
