now i got the maximum by putting my lines x=2,2 and y=1,1 however when i try to find the functions zeroes i get x=y... am i supposed to put that into the equation and evaluate so.... x^2+2(y)y+y^2=x^2?

and they get (x,x,0) as an absolute minima

just wondering if i did right in which the function x^2 will always be positive... and what would happen if i got something that didn't exactly get 0?

Is this Calculus 2? I am doing single variable versions of this in Calculus 1 this week, too.

this is calculus 3... calculus two is more into surface area and integrals... calc 3 is multivariable

Right on. Bye the way, I thought you did great work helping that fellow rationalize the denom. Good teaching!
