MATLAB: How to get z for different x

Question

x = [-2:0.1:2]; 
z=x.*(1-x).*(2-x).*(4-x)/((6-x)-(1-x).*(x-7));

I am getting error. Please correct my problem.

Answer 1

x = [-2:0.1:2];
z = x.*(1-x).*(2-x)./((6-x).*(x-7));

You just forgot a ./

Now you should have a vector

   x = [-2:0.1:2];
   z = x.*(1-x).*(2-x)./((6-x).*(x-7));
   plot(x,z)
