  3. Što znači, napisati (3+ 4)2 = 32 + 42 Bilo bi isto kao kad bismo napisali 49 =25 Što je naravno, POGREŠNO

  4. Došli smo znači, do zaključka da je pogrešno reći (a + b)2 = a2 + b2 GREŠKA!!!!!!!!!

  5. (a + b)2 = (a+b) (a+b) = = a2 + a b + a b + b2 = = a2 + 2a b + b2

  6. a2 (a + b)2 = + 2a b + b2 Prvi na kvadrat Dvostruki prvi puta drugi Drugi na kvadrat

  7. a a2 b2 b

  8. a2 + b2
