13. DESCOMPUNERI IN FACTORI ATENTIE: 1.Pentru tastarea rezultatelor,daca aveti produsul a doua paranteze, una cu %2b si alta cu -, tastati mai intai pe cea cu %2b: DECI tastati (x%2by)(x-y), Nu (x-y)(x%2by) 2. Pentru tastarea rezultatelor,daca aveti produsul a doua paranteze, ambele cu aceeasi operatie, tastati mai intai paranteza care are o constanta mai mica in valoare absoluta: DECI tastati (x-4)(x-5) sau (x%2b5)(x%2b8) 3.Pentru x³ tastati x^2 4. Pentru radical din 3 tastati V3
