Question

(6x - 8y)^3
AYUDAAAAAAAAAA​

Answer 1

Respuesta:

(6x - 8y)³  =  216x³ -864x²y  +1152xy² -512y³

Explicación paso a paso:

• Cubo de diferencia: (a - b)³ = a³ - 3a²b + 3ab² - b³

(6x - 8y)³  =  (6x)³ + (3)((6x)²)(-8y) + (3)(6x)((-8y)²) + (-8y)³

(6x - 8y)³  =  (6³)(x³) + (3)(36x²)(-8y) + (3)(6x)(-64y²) + (-8³)(y³)

(6x - 8y)³  =  216x³ -864x²y  +1152xy² -512y³
