Question

c ) ( x+2 ) . (x+3 ) . ( x+4 )



d) (2x-4) . (3x+1)

​

Answer 1

Resposta:

Explicação passo-a-passo:

(x + 2)(x + 3)  (x + 4) =

(x² + 3x + 2x + 6)(x+4) =

(x² + 5x + 6) (x + 4) =

x³ + 4x² + 5x² + 20x + 6x + 24 =

x³ + 9x² + 26x + 24

D(2x - 4)(3x + 1)

= 6x² + 2x - 12x - 4

= 6x² - 10x - 4)
