I have x^2+5*x+6=0.
I see the roots with the root command but i want to set them as variables to a new function. Also how can i set them to two different displays? I want to write down:
sprintf( 'the first root:%f and the second root:%f')

The output of the roots function can be assigned to a workspace array variable and printed out as you wanted. See the simple example below. You would have to adapt the formatting for complex roots.
x=roots([1,5,6]);
sprintf('the first root:%f and the second root:%f',x)

You just need to swap variables y and x in the function assignment,
x1=y(1);
x2=y(2);
