## Homework Statement

Im trying to find local min and max values. So I have fx and fy. I need to find critical points by setting them equal to 0

4x^3-4y=0 and 4y^3-4x=0

## Homework Equations

4x^3-4y=0 and 4y^3-4x=0

are fx and fy respectively

## The Attempt at a Solution

I just need to know how you would solve this set of 2 equations to get the points (0,0),(1,1) AND (-1,-1)
