## Homework Statement

2x[itex]^{3}[/itex]-3x[itex]^{2}[/itex]y+2xy[itex]^{2}[/itex]-y[itex]^{3}[/itex]=2

## Homework Equations

## The Attempt at a Solution

6x[itex]^{2}[/itex]-(6xy+3x[itex]^{2}[/itex]y')+(2y[itex]^{2}[/itex]+4xyy')-3y[itex]^{2}[/itex]y'=0

y'=[itex]\frac{-6x^{2}+6xy-2y^{2}}{-3x^{2}y+4xy-3y^{2}}[/itex]

My text's solution is the same answer but with every every term having the opposite sign.

I don't see my error and I'm trying to determine why my answer is incorrect.
