Question

(5x + 4 ) (5x + 4) (5x + 4)​

Answer 1

Respuesta:

125 x³ + 300 x² + 240 x + 64

Explicación paso a paso:

(5x + 4 ) (5x + 4) (5x + 4)​

(5 x ( 5 x ) + 5 x ( 4) + 4 (5 x ) + 4 (4)) (5x + 4)​

(25 x² + 20 x + 20 x + 16 )(5 x + 4)

(25 x² + 40 x + 16)(5 x + 4)

25 x² (5 x) + 25 x² (4) + 40 x (5 x ) + 40 x (4) + 16 (5x) + 16 (4)

125 x³ + 100 x² + 200 x² + 160 x + 80 x + 64

125 x³ + 300 x² + 240 x + 64

Espero sea de ayuda!
