Langrage Multipliers, Ending up with huge values

I was trying to use langrage multipliers to solve for the minimum and maximum of the following functions; however, upon using the following commands, I end up with enormous values for the critical points, which I don't think are correct. Please help!:

syms x;

syms y;

syms w;

syms z;

f=5.0*y - 1.0*w*x - 9.0*w*y + 5.0*w*z + 10.0*x*y + x^2

g=0.06964*w*x + 0.1368*w*z + 0.1525*x*y + 0.114*x*z + 0.247*y*z + 0.3672*w^2 + 0.3393*x^2 + 0.4146*y^2 + 0.1505*z^2

Dfw=diff(f,w)

Dfx=diff(f,x)

Dfy=diff(f,y)

Dfz=diff(f,z)

Dgw=diff(g,w)

Dgx=diff(g,x)

Dgy=diff(g,y)

Dgz=diff(g,z)

syms L

assume(L, 'real')

[LSols2, wSols2, xSols2, ySols2, zSols2]=solve([Dfw==L*Dgw, Dfx==L*Dgx, Dfy==L*Dgy, Dfz==L*Dgz, g==1], [L,w,x,y,z])

-And then the values for LSols2, wSols2, xSols2, ySols2, zSols2 are all, gigantic.

It's vastly better to post code, rather than images of code. That way people can copy & paste your code for testing.
