Decide all stationary points to function \(\displaystyle f(x,y)=x^3y^3\) under constraint \(\displaystyle x^3+y^3+6xy=8\)

So basicly this is how they Solved it and I did so as well but I Also have learned that there is stationary point where gardient of constraint is equal to zero

I am aware that you guys Dont understand but it's nr 3 and are those the stationary points or they forgot when gradient of constraint is equal to zero which gives Also this point \(\displaystyle (0,0)\) and \(\displaystyle (2,-2)\)

Edit:svar means answer so are those point correct or?
