taking derivitive of 2xy^2+xy=y(adsbygoogle = window.adsbygoogle || []).push({});

split up to using product rule

[tex] 2x----2 [/tex]

[tex] y^2---2y\frac{dy}{dx} [/tex]

[tex]4yx\frac{dy}{dx}+2y^2+y+x\frac{dy}{dx}=\frac{dy}{dx}[/tex]

[tex] \frac{dy}{dx} (4x+x-1)=-2y^2-y [/tex]

[tex] \frac{dy}{dx}= \frac{-2y^2-y}{4xy+x-1} [/tex]

i am trying to figure out the slope of the equation when y-1

am i doing all this for nothing?
