Hello so I'm suppose to Determine whether the given binoial is a factor of the polymonial P(x) and here's the question (2x-4); P(x)=2x5-4x4+2x2-2x-4 I keep going over and over it and end up with ridiculous numbers -_- please help! thank you

Never mind i got it. You're suppose to divide the 2 into -4 from (2x-4) then do synthetic division!
