I need help with this problem

Question

xyz +yzx - zyx - x²yz

Answer 1

Hi morgan,

 

Working off the assumption that what you need to do is simplify the expression.  Because multiplication is commutative, the order of the variables doesn't matter, so that your problem can be rewritten:

 

xyz+xyz-xyz-x²yz

 

the two middle terms cancel out  (xyz-xyz=0), so we are left with:

 

xyz-x²yz, and we can factor an xyz from each term, leaving just:

 

xyz(1-x).

 

 

Answer 2

xyz + yzx - zyx - x²yz

 

xyz + yzx - zyx - x²yz

 

xyz -x²yz

 

we factor xyz out:

 

xyz(1 - x)
