The definition given is ambiguous:

"there is for every t with F′(t) ≠ 0 an x such that"

does this mean:

"for every t with F′(t) ≠ 0, there is an x, such that"

or :

"there is an x, for every t with F′(t) ≠ 0, such that" — Preceding unsigned comment added by 84.55.114.246 (talk) 16:39, 11 September 2011 (UTC)

I suppose that (a-x^2) should be (a-x)^2; moreover a should be defined. In what I feel the most usual definition the pursued moves on the line x=0 and so a-x is simply x. pietro151.29.178.90 (talk) 06:35, 21 August 2019 (UTC)
