Rank from this order

Rearrange the following MATLAB code to find the root of a quadratic equation, ax2 + bx + C. + Rank the options below. function [rl, r2] =quadroots (a, b, c) rl = 0; r2 = 0; end discr=b^2-4*a*c; if discr >= 0 rl=(-b+sqrt (discr))/(2*a); r2=(-b-sqrt (discr))/(2*a); if a == 0 if br= 0 rl=-c/b; else rl =-b/(2*a); il=sqrt (abs (discr))/(2*a); r2=rl-ilti; rl=rl+il+i;| end else rl='Trivial solution'; end else
