Question: Lagrange multipliers

How do I solve for the Lagrange multipliers of

f(x,y,z)= xyz +x^2 + y^3 +z^4

subject to the constraints:

g(x,y,z)= x^2 + y^2 + 2z^2=4

h(x,y,z) = 3yz + 2xz + xy =6

 

I've never used maple before so am completely lost and need to do this for an assignment=)

 

thanks
