Question

can you help me with this problem?
determine whether the binomial (x-4) iz a factor of the polynomial P(x)= 5x^3-20x^2-5x+20

Answer 1

Are you familiar with synthetic substitution? If so, when you perform a SS you get a remainder of 0 indicating that x-4 is a factor. You can also do long division and look for a remainder of zero. I will show if needed.
