you need to do long division go to here to see how http://tinypic.com/view.php?pic=30ij8jt& … because there is a remainder of 12, x = 2 is not a zero for the polynomial part 2 To find zeros, the remainder of polynomial long division must equal zero. So using that, we can test to see if a value is a zero

umm, if 2 is a zero, then when x=2 the poly goes to zero

amistre64 · Answer

oh, i spose it did say to use the remainder thrm .... seems like a bit of overkill to me

anonymous · Answer

yeah, but i still have to do it! can someone explain how to use the remainder theorem?
