You seem to be having a downside with the definition, and the use of the word multiplicity. If you return to the Wolfram definition of multiplicity you linked you'll see that it refers to a persistent series example.

Well you can regard $f(x)=(x-1)^2$ as a power-series expansion about $x=1$, an identical to: $[scrape_url:1]

[/scrape_url]\cdot (x-1)^0+0\cdot (x-1)^1+ 1\cdot (x-1)^2 + 0\cdot (x-1)^3+0\cdot (x-1)^4 \dots$$ and the example transfers over, with $$f(1)=(1-1)^2=0; f'(1)=2(1-1)=0; f''(1)=2\neq 0$$

$ at $x=1$ on this sense for the reason that first two derivatives are zero, however not the 3rd.

But really the facility series instance is highest considered a generalisation of the easy case of polynomials, and the natural definition of multiplicity in terms of polynomials is most often that the multiplicity $p(x)$ at $a$ is the very best persistent of $x-a$ which is a issue of $p(x)$. This is like announcing that

$ is a double factor of =2^2\occasions 3$.

It is also true that $p(x)$ has multiplicity no less than $r$ at $x=a$ if the primary $r$ derivatives (starting with $f^(0)=f(x)$) assessment to zero at $x=a$. If $f^(r)(a)\neq 0$ the multiplicity is precisely $r$. But this is now not so natural a definition in basic paintings with polynomials.
