Starting from the initial trial solution (x1, x2) (0, 0), interactively apply two iterations of the gradient search procedure to begin solving the following problem, and then apply the automatic routine for this procedure (with  0.01).

Maximize f(x) 6x1 2x1x2  2x2  2x1 2  x2 2

.

Then solve f(x) 0 directly to obtain the exact solution.
