In the section "Curve Inflections", and then in "Lets derive the full formula anyway". The 5th term in the full formula is

-54 * t^2 * x3 * y2

But when the formula is simplified due to being aligned, that 5th term becomes the first term of the simplified formula, but it's sign is flipped.

3 * x3 * y2

I think the signs should be the same.
