The problem is from Numerical Methods. Please show each step of your solution and tell me the theorems, definitions, etc. if you use any.

#### Solution Preview

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- ...

#### Solution Summary

This shows how to manipulate the quadratic formula into a given form.
