me ajudem​

Answer 1

Resposta:

Propriedade: $(a+b)•(c+d) = (a×c+a×d+b×c+b×d$, com a = 3x b=2 c=2x d=1:

$(3x+2)•(2x+1) = (3x•2x+3x•1+2•2x+2•1 = 6 {x}^{2} + 3x +4x + 2 = 6 {x}^{2} + 7x+2$,

Answer 2

Oie, Td Bom?!

$= (3x + 2) \: . \: (2x + 1)$

$= 3x \: . \: (2x + 1) + 2(2x + 1)$

$= 6x {}^{2} + 3x + 4x + 2$

$= 6x {}^{2} + 7x + 2$
