Question

If x+y+z is not equal to zero and x3 + y3 + z3 = 3 xyz , then 2x + 4y - 6 z is =?​

Answer 1

Answer:

x3+y3+z3=3xyz

Step-by-step explanation:

If X + Y + Z is not equal to zero then

{x}^{3} + {y}^{3} + {z}^{3} - 3xyzx

3

+y

3

+z

3

−3xyz

is not equal to zero.

But this contradicts the second information.

Hence, only possible case is when x = y = z = infinity.

This is not practically possible.

Hence, the answer most probably should be undefined.
