Hi ďêãř..
Here is your answer

SOLUTION ==
x³ - 8y³ - 64z³ - 24xyz 
= x³ + (-2y)³ + (-4z)³ - 3(x)(-2y)(-4z) 
= (x - 2y -4z).(x² + (-2y)² + (-4z)² - x(-2y) - (-2y)(-4z) - (-4z)x) 
= (x - 2y - 4z).(x² + 4y² + 16z² + 2xy - 8yz + 4xz)

Based on FORMULA
a³ + b³ + c³ - 3abc = (a+b+c)(a²+b²+c²-ab-bc-ca)

I hope it will help
