Ok, as for x1, we have:
x1= (-b+sqrt(b^2- 4ac))/(2a)
Now we multiply the top and the bottom by (-b- sqrt(b^2- 4ac)) i.e.
x1= [(-b+sqrt(b^2- 4ac))/(2a)]* [ (-b- sqrt(b^2- 4ac))/(-b- sqrt(b^2- 4ac))], so
x1= [(-b+sqrt(b^2- ...
This solution shows how to manipulate the quadratic formula into a given form.
