 PASSO A PASSO

(x2+5x+6).x+2

(x² + 5x + 6)(x + 2)  

(x².x + x².2 + 5x.x + 5x.2 + 6.x + 6.2)
  x³   + 2x²   + 5x²  + 10x  + 6x  + 12
  x³   +      7x²       +      16x           + 12

(x² + 5x + 6)(x+ 2) = x³ + 7x² + 16x + 12
 

DIRETO

(x² + 5x + 6)(x+2) =
x³ + 2x² + 5x² + 10x + 6x + 12
x³ +   7x²  + 16x + 12  


(x² + 5x + 6)(x+2) = x³ + 7x² + 16x + 12
