Answer:
x-4 is a factor
Step-by-step explanation:
To know the factor, we simply equate the binomial to zero
After doing this, we substitute the x-value into the polynomial. If the answer gotten is zero, then it is a factor of it
Let us try x -4
set x -4 = 0
x = 4
Find f(4)
That will be ;
2(4)^3 + 3(4)^2 -39(4) - 20 = 0
, so that 
but 
. Since 
, it follows that 
, and since 
, it follows that 
, which means 
.
