Homework Statement
Consider the curve x^2+xy+y^2=27
Homework Equations
Find all points on the curve where the lines tangent to the curve are vertical
The Attempt at a Solution
I found dy/dy = (-2x-y)/x+2y)
and I think I found the equations of lines visually to be x=6 and x=-6 but I'm not sure how to show the work.
