1. The problem statement, all variables and given/known data Find dy/dx by implicit differentiation: 6x^2+8xy+y^2=6 2. Relevant equations n/a 3. The attempt at a solution I'm using y'=(dy/dx) I found the derivative of the above problem. 12x+8xy'+10y=0 (I used the product rule to find the derivative of 8xy') 12x+8xy'+10y=0 8xy'=-12x-10y xy'=(-12x-10y)/(8x) I checked the answer in the back of the book and it was y'=(-6x-4y)/(4x+y) I'm not sure where I missed a step or a calculation error Thanks!!
