Karush-Kuhn-Tucker (KKT) conditions: motivation and theorem

Oh thank you from Vietnam !

I have a doubt. It is mentioned in the video that for 2 constraints, there are four things to check. I understood that we are looking for the solution on the boundaries of the contraint set where at least one of the constraints are active. But the optimum solution can be a point in the interior of the constraint set where no constraints are active. How will I get the internal optimum point with unconstraint optimization technique?

It's just the condition of stationary, simple derivative (Gradient ) of the function with constraints.
