answer to a quadratic function

Hi

how do I get both of my solution in a quadratic function? I only have the answer for x1

Answer 1

[Matt J]

For example,

>> roots([1,5,2]) %roots of x^2+5*x+2

ans =

   -4.5616
   -0.4384

Hm, thanks for the answer. But when I do that the answer is not right.

this is the function, and how i didi it

1. y = x^2+ x − 12,

function [x1, x2] = myquadratic(a,b,c)

a = 1;

b = 1;

c = -12;

X = sqrt(b^2-4*a*c);

Y = 2*a;

x1 = (-b + X) / Y;

x2 = (-b - X) / Y;

here I only get

ans= 3

but i would like to get

ans=-4 as well

In all likelihood, that is because you did not call the function with 2 output arguments.

K>> [x1,x2]=myquadratic()

x1 =

     3


x2 =

    -4
