Show that the given value ofcis a zero ofP(x), and find all other zeros ofP(x) (Enter NONE in any unused answer blanks.)

P(x) = -2x3 + 2x2 + 4x- 4,c= 1.

I figured that all out, and 1 does bring a remainder of 0.

And I believe my end equation is (x-1) (-2x^2+4)

From there, I don't know how to find the other zeros... and my book doesn't help at all.

Thanks guy
