Step-by-step explanation:
Let be
, which can be simplified solely by algebraic means. We proceed to describe all the steps needed for simplification:
1)
Given.
2)
Distributive and associative properties.

Answer:
i believe d. I could be wrong
Step-by-step explanation:
The Lagrangian is

with critical points where the partial derivatives vanish.



Substitute
into the last equation and solve for
:

Then we get two critical points,

We get an absolute maximum of
at the second point, and an absolute minimum of
at the first point.
