## Homework Statement

Derivative of [tex]\frac{y - 1}{y^2 - y + 1}[/tex]

## Homework Equations

## The Attempt at a Solution

The solution is [tex]\frac{y^2 - 2y}{(y^2 - y + 1)^2}[/tex] but in my work, the answer will have something to the 4th power on the top which will be impossible to cancel out. What have I done wrong?

Edit: Never mind, I see my mistake
