pq Formula (quadratic formula)

The pq-formula is the better option compared to the more common quadratic formula (or ABC formula). It is about solving quadratic equations.

To get the pq you have to go like this:

ax² + bx + c = 0 | : a
x² + b/a x + c/a = 0
x² + px + q = 0

Now you can use the much more practical pq-formula shown on the left of this website.
