part b

In this problem we shall consider the effect of computer arithmetic in the evaluation of the quadratic formula 1,2 for the roots of p(x)-ax2 + bx + c. (a). Write a Matlab function, call it quadroots, that takes a, b, c as input and returns the two roots as output. The function may start like this: function [ri, r2] quadroots (a,b,c) % input: a, b, c: coefficients for the polynomial ax^2+bx+c-o. % output: r1, r2: The two roots for the polynomial
