You will be required to know the quadratic formula for your exam next week. Some of you have struggled with this so today we’re going to have some fun learning it once and for all. You are going to learn to SING the quadratic formula, to the tune of the popular some “Pop goes the weasel”.

If you can’t remember the song, here it is: Pop goes the weasel

Now for the new lyrics:

Instead of:

All around the mulberry bush,
The monkey chased the weasel.
The monkey thought ’twas all in fun. 
Pop! goes the weasel!

You will sing:

x equals negative b
plus or minus the square root
of b squared minus 4ac
all over 2a!

But before you start, I will show you how it’s done….
