WebThat is only true once you know xy. The infimum of all values (x + 2y)2 in the domain xyz = 32, x, y, z > 0 is clearly zero. Alternatively, you assumed (x + 2y)2 = 8xy, but that's only … WebFeb 28, 2015 · (In some sense, the solution below is a Lagrange multiplier solution, but without the calculus). In your problem, the first step that I will take is to change variables to $z=\sqrt {2}y$. Then, your problem is to maximize or minimize $x^2+z^2$ subject to $x^2-\frac {1} {\sqrt {2}}xz+z^2=1$.
