What did your sketch look like, what do you think the positive root corresponds to?
Well there's two positive roots on my sketch

Care to share? Its probably no secret that there should be only one.

I agree but only one of those roots (intersection point) is positive.

Are we talking about the x value because then it would be 4x-2?

Yes. The y value for a root is 0 so its meaningless to talk about its sign. I guess youre thinking about the intersection point, rather than the root (function argument/x value). As you say, you want the 4x-2 branch, hence -(2-4x).
