okay thank you guys, Precal, are you doing it with a negative three or a positive three? it looks like you did it with a positive and just wrote a negative but I cant tell, just asking

p(3)=151 that is one way to double check yourself

precal i thought your suppose to us turn the 3 into a 3 when you sythethic divide.

if you are told (x+3) then yes x=3 but we were given p(3) that means x=3 the question here is, is 3 a zero? since my remainder is 151, 3 is not a zero

Oh ok i just saw the 3 and thought i should be positive.. ..... If you have a remainder its not a zero.

correct and if it is a zero then the remainder will be zero
