Put constant term on the right:
Multiply by 4 times the lead coefficient:
Add the original first degree term coefficient squared.
Factor the perfect square on the left:
^2\ =\ 56)
Take the square root of both sides (positive and negative)
Add opposite of the new constant term on the left:
Multiply by the reciprocal of the coefficient on 
:
And simplify:
Fascinating! I wonder what happens when you apply this method to the general quadratic.
^2\ =\ b^2\ -\ 4ac)
Would you look at that! The quadratic formula.

My calculator said it, I believe it, that settles it
