Homework Statement
See attached for problem
Attempt at solution
∂f/∂x = 3x2+12x
∂f/∂y = 3y2-12y
Factorise
x(3x+12)
x=0 or,
3x+12 = 0 → x= -4
y(3y-12)
y=0 or,
3y-12=0 → y=4
I find the next stage difficult, because there are no mixed terms in the polynomial any of the values i substitute into another gives me 0, because of this i need help finding the stationary points, I'm fine with classifying them
Thanks
