## Homework Statement

g(y)=(y-1)/(y

^{2}-y+1)

## Homework Equations

## The Attempt at a Solution

After I take a derivative, I get

g'(y)=[y(y-2)]/(y

^{2}-y+1)

^{2 }

However,

(y

^{2}-y+1)

^{2 }does not have any solutions. Am I right that I just throw it away? As an answer, I only leave

y1=0, y2=2

Is that correct?
