what?
quadratic formula is (-b (+/-) root (b^2 -4ac))/2a

I've seen a rich man beg, I've seen a good man sin
I've seen a tough man cry, I've seen a loser win
And a sad man grin, I heard an honest man lie

you use the quadratic formula when you have an A, B, and C value from something like
Ax^2+Bx-C

You cant just say quadratic formula of 7 and 1/3

3X 2 - 22X + 7 = 0
