    The answer to your question are letters A, C and D.

    Step-by-step explanation:

    To factor this polynomial we need to look for the common factor of the three terms.

    To find it, get the greatest common factor

    140 28 14 2

    70 14 7 2

    35 7 7 5

    7 7 7 7

    1 1 1

    Greatest common factor = 2 x 7 = 14

    Factor the polynomial

    140c + 28 - 14a = 14 (10c + 2 - a)

    Factor only 7 7 (20c + 4 - 2a)

    Factor only 2 2 (70c + 14 - 7a)
