Hi.
Good thinking, but you made a mistake
OKAY
Not okay, you divided by x; you can do that, but this is only for ; and x = 0 is a solution!
So
is better,
now you know x = 0 is a solution and x²-8 = 0 leads to the other solutions; you still have to solve x²-8= 0, tho.
The last step seems to be unnecessary
// ^(1/3)
You're welcome.
