Write a function file that computes the roots of a quadratic using the form for x+ and x1 that are least susceptible to cancellation error. Also write a script file to find the roots of
ax2 +bx+c=0
For reference, your function file will have the structure
function [xp,xm] = quadform(a,b,c)
if (b<0)
xp =
xm = else
xm =
xp = end
Calculate the roots for the following
a) a = 1;b = 105;c = 1.
