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
0
The answer is (x - 4)
