How to solve quadratic equations

Hi, I have a few lines of code, really dont know whats wrong with it? Any one?

y=zeros((length(x_cell{1}{1})),1);
x=x_cell{1}{1};
for n=1:length(x)
   f(n)=fsolve('(1/238.6318^2)*(x(n)-222.8970)^2+(1/115.8401)^2*(y+95.96210^2)=0','y');
end

Thanks

Jing

try

syms x y;
f = solve((1/238.6318^2)*(x-222.8970)^2+(1/115.8401)^2*(y+95.96210^2),y);
f1 = matlabFunction(f);
out = f1(x);
