PRODOTTI NOTEVOLI

INDIETRO


FORMULE DI PRODOTTI NOTEVOLI:

• ( A+B ) . (A-B) = A2-B2
  

(X+2Y) . ( X-2Y) = X2-4Y2

• ( A+B )2 = A2+2.A.B+B2
  

( 2A+ 2B)2 = 4A2+8AB+4B2

• ( -A-B )2 = A2+2.A.B+B2
  

( 2A+ 2B)2 = 4A2+8AB+4B2

• ( A-B )2 = A2-2.A.B+B2
  

( 2A+ 2B)2 = 4A2-8AB+4B2

• (-A+B )2 = A2-2.A.B+B2
  

( 2A+ 2B)2 = 4A2-8AB+4B2

• (A+B)3= A3+3A2B+3AB2+B3
  

(2A+2B)3= 8A3+12A2B+12AB2+8B3
