How do you use the method of Lagrange multipliers to find local maxima and minima of a multivariable function subject to a constraint?

The method of Lagrange multipliers is a strategy for finding the local maxima and minima of a function subject to equality constraints. This method introduces an auxiliary function called the Lagrangian, which incorporates the original function and the constraint using a new variable called the Lagrange multiplier. By solving the system of equations formed by the partial derivatives of the Lagrangian, one can find the critical points that potentially represent the local maxima or minima of the original function under the given constraint.
