Question

5 multiplicaciones de polinomios​

Answer 1

Respuesta:

(2x+1).(3x+2)= 2x.(3x+2)+1.(3x+2)= 6x2+4x+3x+2=6x2(+4x+3x)+2=6x2+7x+2.

(x-1).(x+2)=x.( x+2)-1.(x+2)= x2+2x-x-2=+x2(+2x-x)-2=x2+x-2.

(3x+3).(x2+2x+1)= 3x.( x2+2x+1)+3.( x2+2x+1)= (3x3+6x2+3x)+(3x2+6x+3) = 3x3+9x2+9x+3.

Espero que te sirva ☺️
