From another website comes this...
This is the original equation. ax^2 + bx + c = 0
Move the loose number to the other side. ax^2 + bx = �c
Divide through by whatever is multiplied on the squared term.
Take half of the x-term, and square it. Add the squared term to both sides.
x^2 + (b/a)x + (b^2/4a^2) = �(c/a) + (b^2/4a^2)
Simplify on the right-hand side; in this case, simplify by converting to a common denominator.
x^2 + (b/a)x + (b^2/4a^2) = �(4ac/4a^2) + (b^2/4a^2)
Convert the left-hand side to square form (and do a bit more simplifying on the right).
(x + b/2a)^2 = (b^2 � 4ac)/4a^2
Square-root both sides, remembering to put the "�" on the right.
x + b/2a = � sqrt(b^2 � 4ac)/2a
Solve for "x =", and simplify as necessary.
x = [ �b � sqrt(b^2 � 4ac) ] / 2a
