du klammerst aus:
x(x hoch2- 6x +9)
dann hast du x= 0
und (...) =0
in der Klammer wendest du pq Formel an

Googel mal die Aufgabe , dann kommt das bei raus ;D

Sorry, weiter, als bis zu meiner Gitarre bin ich nicht gekommen. Ich hatte sie plötzlich in der Hand und hab nicht weiter an Mathe gedacht. Drum kommt jetzt das, woran ich mich wage erinnere:

Zweite Ableitung nullsetzen -> Extremstellen
Dritte Ableitung nullsetzen -> Wendepunkt

1. Ableitungen bilden
2. Nullstellen f(x) = 0
3. Extrema f´(x) = 0
Maximum f´´(x) < 0

Minimum f´´(x) > 0
4. Wendepunkt f´´(x) = 0
5. Sattelpunkt f´(x) = 0
6. Graphen von f,f´,f´´

7. Monotonie
monoton steigend f´(x) 0
monoton fallend f´(x) < 0

8. Kurvenkrümmung
rechtsgekrümmt f´´(x) < 0
linksgekrümmt f´´(x) 0


9. Grenzwerte lim f(x)...

Fertig.. 5min Sache, eigentlich müsste man das noch Beweisen bzw Lücken etc auffidnen und ggf. heben aber das lass ich hier mal weg.
