Ignore the *******< br/ > *******

then if

Yes, that's a perfectly good proof. The basic idea, of course, is that, for x not equal to 2, so this problem is really "linear" and you can do it that way.

Plato's reply points out a certain flaw in the original proof:

what if |x - 2| = 0?

your proof should start with:

if ....

this allows you to multiply and divide by (x - 2) without fear of it being undefined.
