I shake my head and I rattle my brains.

Algebra is driving me insane.

Axis of Symmetry... Discriminant....

If only I knew the quadratic formula!

Negative b divided by 2a

Gives me the line of symmetry

But the discriminant? I haven't a hint.

If only I knew the quadratic formula!

b squared minus 4 a c

Tells me how many roots that there will be

Zero is one, negative is none,

Positive is two... the quadratic formula!

Put them together and you know the whole thing,

Algebra can really swing.

On the test today, I'll make an A!

As long as I know the quadratic formula,

I've got to remember the quadratic formula!

Negative b plus or minus the root

(snap,snap)

b squared minus 4 a c

And under the line (snap)

2 a looks fine...

YES! I know the quadratic formula!
