MATLAB: I cannot get the function to solve quadratic equations to work. Can anyone help

functionsquadratic equations

function [disc, quadRoots] = Q1_15024248(a,b,c);
disc = b^2-(4*a*c);
if disc < 0
     disp('NaN')
elseif D==0 
        quadRoots = -b/2*a
else
  x1 = -b + sqrt(disc)/(2*a);
  x2 = -b - sqrt(disc)/(2*a);
  quadRoots = [x1,x2];
   end
end
it leaves me with the error message:
 function [disc, quadRoots] = Q1_15024248(1,4,4);

Put your function code in a file called Q1_15024248.m somewhere on the MATLAB path (e.g., your working directory).
