Yes, Geoffrey, it is a good way to check. However, it is only one of
many good ways to check.

The problem is that "simplified," as we have often defined it for our
beginning algebra students, is not always simpler. Moreover, to enforce
the rule of "simplified", we deny credit for mathematically correct
work. This reinforces the student's notion that math is arbitrary, not
logical and consistent.
