Moin moin!
Ich bin leider nicht so Leuchte in Mathe und versuche gerade die Lösung des Profs zu verstehen.
Bis zur markierten Stelle verstehe ichs noch.
Er holt die 2x - 2 einfach rüber und hat kommt dann auf die Gleichung
x² + 2x - 3 < 0

aber was zur Hölle macht er danach?
Fänd es super, wenn ihr mir da helfen könntet.

Gruß Michael
