Answer 1

Resposta:

3 ( 5x + 4 ) . ( x + 3 ) . ( 2x + 8 )

3 ( 5x² + 19x + 12 ) . ( 2x + 8 )

( 6x + 24 ) . ( 5x² + 19x + 12 )

6x . 5x² + 6x . 19x + 6x . 12 + 24

5x² + 24 . 19x + 24 . 12

30x³ + 234x² + 528x + 288

Answer 2

Explicação passo-a-passo:

3(5x+4)(x+3)(2x+8)

(15x+12)(x+3)(2x+8)

(15x²+45x+12x+36)(2x+8)

(15x²+57x+36)(2x+8)

30x³+120x²+114x²+456x+72x+288

=>30x³+234x²+528x+288
