    Answer

    (x – 4)

    Step by step explanation

    To find the factors, plug in the x values in the given equation and see which value of x makes the equation equal to zero.

    Here (x – 4) is a factor.

    Therefore, x = 4

    when we plug in x = 4 in the given expression, we get zero.

    Let’s check it out.

    3(4)^3 + 8 (4)^2 – 87(4) + 28

    192 + 128 – 348 + 28

    348 – 348

    The answer is (x – 4)

    Thank you.
