You can put this solution on YOUR website!
Factor:
You can only extract a factor if it exists in all three terms. So, for the numerical coefficients, you have 4, -12, and 16:
2 factors of 2 are common to all three, so take out 
Leaving you with:
)
All terms have at least 2 factors of x, so take out  , leaving you with:
)
All terms have at least 5 factors of y, so take out  , leaving you with:
)
Finally, all terms have at least 2 factors of z, so take out  , leaving you with:
)
As your final answer.
