(c) Should read 2x^2 + y^2 = 2.
I'm working on a constrained optimization problem, but I can't remember how to represent the system of first order conditions:
a. x - 4xz = 0
b. y - 2yz = 0
c. 2x^2 + y^2 = 0
in matrix form so that I can solve using matrix algebra? The polynomial aspect is throwing me off, I think. Cheers.
