Answer 1

x-4 is a factor

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
