Question

How do you factor completely `vwx + wxy - xyz`?

Answer 1

`vwx+wxy-xyz = x(vw+wy-yz)`

Explanation:

All of the terms are divisible by `x`, so we can separate that out as a factor:

`vwx+wxy-xyz = x(vw+wy-yz)`

It is not possible to factor this further.

Note that if there was an additional term `-vxz` in the original expression then we would be able to factor further:

`vwx+wxy-xyz-vxz = x(w-z)(v+y)`

Was this omitted by accident?
