In the first two equations, λ λ can't be 0, so we may divide by it to get x = y =2/λ. x = y = 2 / λ. Substituting into the third equation we get. 2 2 λ +22 λ =100 8 100 =λ 2 2 λ + 2 2 λ = 100 8 100 = λ. so x = y = 25. x = y = 25.

Sorted by: 6. The sign comes from the following reasoning: With equality constraints g(x) = 0 g ( x) = 0, for a point x x to be optimal, any perturbation to x x that changes f f must also violate constraints g g become (no matter if g g becomes positive or negative, important thing is that it is no longer zero), hence the gradient of f f must ...

This does not fit with your second or third equation, so you must set y = z = 0; but you can adjust x to match your final equation and thus get candidates for an extreme point with the zero derivative.
