Is there a
+1
at the end? If so, what have you tried?

Every minus or positive sign stands for another term. Try to order the terms in that way the variables have the common variables, as in:

xyz + x - xy + yz - y - xz - z

Arranged in that way, the red terms have a common x, the blue ones a common y and the green ones a common z as variable. Try it with this!

can you upload a picture of the question. If there is a +1 at the end, there is a fairly obvious factorization, or is it og part of a larger question where it makes sense to add/subtract 1?

The other two parts are "factorise fully" type questions, and the only way you can do the same here is if there was a +1 at the end.

If its just for practice, I'd assume there is a +1 at the end and factorise that. It has a few similarities with part b). If its some form of assessment, check with your teacher/course.

It's just for practice and I think like you, thank you
