Homework Statement
For:
f(x,y)=(x+y)/(x^2+2y^2+6)
Find the stationary points of f
Homework Equations
The Attempt at a Solution
To find a stationary point the first partial derivative must equal zero, correct?
I've found the first partial derivatives using the quotient rule but my problem is, I can't rearrange them for y= or x= so I can substitute them into one equation and solve for x or y. What do I do now?
