okay two words.
ax^2 + bx + c = 0
D = b^2 - 4ac
x = (b +/- sqrt(D)) / 2a
Works every time.
If you copy it down correctly. It should be
x = (-b+/-sqrt(b
2-4ac))/2a
Gotta love the quadratic formula. It will always work. But make sure you are in standard form (ax
2+bx+c=0) before completing the square, using synthetic division, factoring or use the quadratic formula.
I see I forgot a minus sign there..
Sorry about the test bahamut.
