It really just comes with time and practice. The denominator is very easy, assume we have ax^2+bx+c. Right away the denimonator is 2*a, that's it! The numorater is harder, think of it as:

 

Minus the middle coeficient (-b) 

Plus Minus 

Sqrt of ((b again :D)^2   -   (4*(The other two coefficents not mentioned before in the numerator (a*c)))

 

Hope that helps!
